ABSTRACT: Recently, CuH-catalyzed reductive coupling processes involving carbonyl compounds and imines has become an at-

tractive alternative to traditional methods for stereoselective addition to carbonyls due to the ability to use readily accessible and

stable olefin-derived pronucleophiles as surrogates for organometallic reagents. However, the inability to use aldehydes, which tra-

ditionally reduce too rapidly in the presence of copper hydride complexes to be viable substrates, has been a major limitation. We

show that by exploiting relative concentration effects through slow addition, we can invert this intrinsic reactivity and achieve the

reductive coupling of 1,3-dienes with aldehydes. Using this method, both aromatic and aliphatic aldehydes can be transformed to

valuable products with high levels of diastereo- and enantioselectivity and in the presence of many useful functional groups. Further-

more, using a combination of theoretical (DFT) and experimental methods, important mechanistic features of this reaction related to

stereo- and chemoselectivity were uncovered.

■ INTRODUCTION

The addition of nucleophilic organometallic reagents, such

as those based on Mg (Grignard), B, Si, Sn and Zn, to carbonyl

derivatives is a key reaction for C–C bond formation.1 Accord-

ingly, the development of methods to accomplish this transfor-

mation in a catalytic, stereoselective manner have been the sub-

ject of widespread research efforts.2 Recently, breakthroughs in

transition metal catalysis have enabled the use of olefin-derived

nucleophiles, one of the most convenient and readily available

classes of compounds, as surrogates of traditional organometal-

lic reagents in carbonyl addition processes.3-10 Following pio-

neering work by Krische using Rh4a,b, Ru5, Ir6, and Ni cata-

lysts,7e several research groups, including ours, have developed

a number of CuH-catalyzed processes for reductive C–C bond

formation from π-unsaturated pronucleophiles (Figure 1A).9,10

Each of these metals is associated with distinct catalytic

mechanisms and complementary reactivity, and hence, features

respective advantages and deficiencies. In the case of Cu, the

most notable advantages include mild conditions, high stereose-

lectivity, and exceptional tolerance for polar functional

groups.9,10 On the other hand, the proclivity of CuH intermedi-

ates to participate in direct reduction of carbonyl compounds

has so far limited the generality of this strategy: to date, only

the functionalization of ketones and imines using relatively ac-

tivated alkenes such as allenes, enynes, styrenes have been suc-

cessfully accomplished (Figure 1B).9,10 The conspicuous ab-

sence of aldehydes, the most common class of electrophiles in

carbonyl addition reactions, can be explained by the rate of their

direct reaction with CuH species, which is sufficiently high that

the olefinic partner typically does not have the chance to partic-

ipate in hydrocupration.11

With the aim of addressing this important limitation, we

herein report the expansion of the scope of CuH-catalyzed re-

ductive olefin–carbonyl coupling to aldehyde starting materials,

using a combination of ligand-conferred regioselectivity and ki-

netic control through metered addition. To prove our concept,

we selected 2-substituted 1,3-dienes as relatively unactivated

model pronucleophiles (Figure 1B). 2-Substituted allyl groups

are difficult to introduce using stoichiometric organometallic

reagents, and few catalytic methods have been reported for their

stereoselective installation.2,12

Considering previous mechanistic studies,9f we envisioned

that our proposed transformation would proceed through hydro-

cupration of a diene to generate a mixture of allylcopper com-

plexes represented by II (Figure 1C). One or more of these spe-

cies could engage an aldehyde coupling partner in a stereose-

lective migratory insertion process to form the copper alkoxide

III, from which metathesis with a hydrosilane (IV) would re-

generate LCuH (I) and the desired product (V) in silyl-protected

form. Clearly, the diene hydrocupration must be faster than the

rapid direct reduction of the aldehyde, which is contrary to the

intrinsic kinetic preferences of these elementary reactions (18.5

vs. 13.9 kcal/mol calculated free energy barriers for diene and

aldehyde hydrocupration respectively, see below). In this article,

we describe the optimization of a reaction system that displays

this inverted chemoselectivity, its applications to the highly re-

gio-, diastereo- and enantioselective allylation of both aliphatic

and aromatic aldehydes, and mechanistic studies that explain

the origin of these selectivities.

■ RESULTS AND DISCUSSION

We initiated our study by examining reactions of p-

anisaldehyde (1a) and 2-phenyl-1,3-butadiene (1b) under re-

action conditions previously described for CuH-catalyzed

ketone allylation.9e,f With (S,S)-QuinoxP*(L1) as the ligand,

the desired product 1 was obtained in 48% yield, with exclu-

sive branched-selectivity and excellent preference for the in-

dicated diastereomer (11:1 dr). However, the major diastere-

omer was formed with only a moderate level of enantiose-

lectivity (68:32 er, Table 1, entry 1). No desired homoallylic

alcohol 1 was obtained when (R)-DTBM-SEGPHOS (L2)

was used as the ligand: complete reduction of the aldehyde

was observed instead (Table 1, entry 2). JosiPhos13 deriva-

tive SL-J011-1 (L3), a ligand which had been employed with

good results in ketone allylation,9f was also examined. The

corresponding test reaction provided 1 in moderate (57%)

yield, with 8:1 dr and 85:15 er (Table 1, entry 3). Further

evaluation of commercially available common chiral ligands

revealed (S,S)-Ph-BPE (L4) to be optimal (Table 1, entry 4),

providing 75% yield of 1 was obtained with excellent dr

(21:1) and er (96.5:3.5). Table 1. Evaluation of Reaction Conditions for the CuH-Catalyzed

aConditions: 1a (0.1 mmol, 1 equiv), 1b (2 equiv), Cu(OAc)2 (0.01

or 0.05 equiv), ligand (0.012 or 0.06 equiv), dimethoxy(me-

thyl)silane (4.0 equiv) in solvent (0.2 mL). 1a was added slowly by

syringe pump (1.0 mol/L, 1.0 uL/min); see the Supporting Infor-

mation for details. bYield and diastereomeric ratio were determined

by 1H NMR spectroscopy of the crude reaction mixture, using di-

bromomethane as an internal standard. cEnantiomeric ratio was de-

termined by HPLC or SFC analysis on commercial chiral columns,

and the relative configuration of 1 was determined by comparing

its NMR and optical rotation data with reported data.14 dWithout

metered addition. eWith slower addition rate (1.0 mol/L, 0.5

uL/min).

With a slight increase in reaction temperature (40 ˚C),

both the yield and er diminished slightly (Table 1, entry 5).

Furthermore, the results were very sensitive to the catalyst

loading: excellent yield (90%) was achieved without losing

high diastereo- and enantioselectivity (13:1 dr, 94:6 er) by

decreasing the catalyst loading from 5.0 to 1.0 mol% (Table

1, entry 6). Lowering the temperature to 0 ˚C proved to be

beneficial, increasing the yield to 94% (Table 1, entry 7). Me-

tered addition of the aldehyde is also important for this allyla-

tion process: by adding the aldehyde in a single batch at the start

of the reaction, only 33% of target product could be observed.

However, extremely slow addition rates will decrease the enan-

tioselectivity slightly and are not advantageous for the yield

(Table 1, entry 8 and 9).

We next explored the scope of the asymmetric reductive

coupling of aldehydes with 1,3-dienes. As depicted in Table 2,

a range of chiral homoallylic alcohols were prepared in excel-

lent yields and levels of enantiomeric purity. Simple benzalde-

hyde was successfully transformed into the corresponding

homoallylic alcohol 2 in good yield with moderate diasterose-

lectivity, but high enantioselectivity. Notably, aliphatic primary

(3, 4), secondary (5), and tertiary (6) aldehydes were also com-

patible substrates with our protocol, providing uniformly excel-

lent yield, dr and er. Using ferrocenecarboxaldehyde, we ob-

tained enantiomerically enriched ferrocene derivative 7. Fur-

thermore, substrates containing heterocycles, such as a furan (8),

a thiophene (9) and an indole (10), were all tolerated under the

reaction conditions. A thioether could also be effectively con-

verted into secondary alcohol 11 with good stereoselectivity.

Next, we assessed the scope of 1,3-diene pronucleophiles

(Table 2). The reaction proceeded efficiently with dienes bear-

ing electron-donating (7, 8) or electron-withdrawing (9, 10) aryl

substituents at 2-position. Various heterocycles are well toler-

ated on the diene component, including a thiophene and an in-

dole, reacting efficiently with both aromatic and aliphatic alde-

hyde partners (11-14) with excellent diastereo- and enantiose-

lectivity.

2-Alkyl substituted dienes could also be effectively con-

verted. For instance, 2-cyclohexyl-1,3-butadiene coupled well

with a range of vinyl (15) and aliphatic aldehydes (16-18) with

high selectivities, although the yields are moderate. In particular,

simple aliphatic aldehydes such as acetaldehyde are suitable

starting materials for this reaction (16). Even extreme steric

bulk on both components could be tolerated: using pivaldehyde

and an adamantyl-substituted diene, homoallyl alcohol 19 was

obtained with moderate yield (48%) and excellent diastereo-

gent, providing 20 with good yield and useful stereoselectivity.

■ MECHANISTIC STUDIES

By analogy to other copper-catalyzed reductive olefin–ke-

ton9b,f and olefin–imine coupling9a reactions, we proposed that

the current reaction proceeds through the mechanism illustrated

in Figure 1C. Previous computational and experimental inves-

tigations of related transformations have revealed, in intricate

detail, the sequence of events and controlling factors that dictate

the regio-, diastereo- and enantioselectivity observed in these

transformations.9f However, we were interested in several ques-

tions pertaining to the mechanism and selectivity that are par-

ticular to this aldehyde allylation. First, we wanted to confirm

the feasibility of our proposed series of elementary steps, as

well as their relative rates, their reversibility, and the identity of

the selectivity-determining step(s). It is important to note, how-

ever, that metered addition of the aldehyde, which presumably

maintains a low steady-state concentration of aldehyde, is cru-

cial to obtaining high yields of product. Thus, it is necessary

that our model to account for this effect. Second, we hoped to

explain the stereochemical outcome of our reaction. Specifi-

cally, our rationale should both identify the step(s) that control

the diastereo- and enantioselectivity (allylcopper isomerization,

C–C bond formation, -bond metathesis, or a combination

thereof), as well as the specific ligand–substrate interactions re-

sponsible for destabilizing the disfavored stereoisomeric path-

ways. Finally, we wanted to confirm experimentally that com-

peting aldehyde vs. diene insertion into a copper(I) hydride

complex determines the chemoselectivity with regard to reduc-

tion vs. the desired coupling.

structures for the C–C bond formation step, leading to the major stereoisomer (left), the minor diastereomer (middle) and the minor

enantiomer (right) of product 2. See the Supporting Information for details.

We first turned to DFT-based modeling to address the first

two questions. The computed Gibbs free energy profile, using

model diene 1b and benzaldehyde (1c) as model substrates, is

shown in Fig. 2. Starting from L*CuH (I), where L* = (S,S)-

Ph-BPE, irreversible hydrocupration of 1b takes place prefer-

entially through its s-cis conformation and with facial selectiv-

ity to generate the S enantiomer of branched allylcopper com-

plex IIa. We found that (S)-IIa can isomerize rapidly to a nearly

isoenergetic linear isomer IIb-cis, in which the Ph and Me al-

kene substituents are mutually cis. While this isomerization is

associated with an energetic barrier of 7.1 kcal/mol (TS3-cis),

there also exists a second, slower isomerization pathway (13.0

kcal/mol barrier) leading to more stable linear isomer IIb-trans

(4.0 kcal/mol more stable than IIa), in which the Ph and Me are

mutually trans.

In accordance with the Curtin–Hammett principle, the iso-

mer of II (e.g., IIa, IIb-cis, IIb-trans) through which the reac-

tion proceeds will depend on the rate of the subsequent addition

step relative to the isomerization processes. However, prior to

further elaboration on this aspect, we first need to more pre-

cisely consider the effect of slow addition of aldehyde on the

mechanistic model in general. While it is conventional to plot

energy diagrams using standard thermodynamic parameters,

(i.e., those at 1 M solution for solutes), true relative free ener-

gies depend on the concentrations of the species involved. In

cases where two reactants might have concentrations differing

by many orders of magnitude during steady-state catalyst turn-

over, it is particularly important to consider relative concentra-

tion effects in the interpretation of an energy diagram.15

Accordingly, in the reaction under consideration, we noted

that the metered addition of aldehyde over several hours should

ensure that the concentration of the aldehyde is very low rela-

tive to the other reactants. The presence of this concentration

disparity is equivalent to raising the free energy of all states

wherein aldehyde is associated with the catalyst (Figure 2, high-

lighted in grey) relative to states in which the aldehyde is free

(in white). Indeed, we find that if, by relative concentration ef-

fects, TS1 is raised in energy by more than about 4.6 kcal/mol

relative to TS2a, hydrocupration can be favored over direct re-

duction of the aldehyde, as is observed in the reaction.

A less obvious consequence is that the reaction of the cop-

per allyl species is also slowed, which has implications on re-

versibility of allylcopper isomerization. We examined eight di-

astereomeric transition states for allylcopper addition to the al-

dehyde (Figure 4, boxed and labeled TS4-cis/trans). Consider-

ing standard free energies alone, it would appear that reaction

of the cis-allyl complex IIb-cis through (S,S)-TS4-cis is suffi-

ciently facile that competing isomerization to the more stable

IIb-trans should be kinetically precluded. However, with spe-

cies highlighted in grey raised in energy by the amount (>4.6

kcal/mol) required to avoid direct aldehyde reduction, reaction

of IIb-cis with aldehyde through the TS4-cis transition states

necessarily become more challenging than reversible isomeri-

zation to IIb-trans. In this scenario, the predicted major reac-

tion pathway (highlighted in blue) proceeds through (S,R)-TS4-

trans, leading to the diastereomer of product that is experimen-

tally observed to be predominant ((S,R)-V).

We next examined the transition state structures to eluci-

date the origin of stereoselectivity in the addition step. Mono-

meric complexes of Ph-BPE-ligated copper are known adopt a

conformation whose steric profile is well approximated by a

quadrant model.16 For instance, in the preferred six-membered

cyclic transition state (Figure 3, left panel),17 the largest substit-

uents of both the allyl component and the aldehyde component

are directed into the less hindered (white) quadrants during the

C–C bond formation. In contrast, minor enantiomer of product

can form if the aldehyde attacks the opposite face of the diene

(Figure 3, center panel). However, a steric clash is created be-

tween the aryl substituent of the diene and the Ph substituent of

the ligand (bottom-right quadrant), which destabilizes this

structure. Furthermore, unfavorable steric interactions between

the aldehyde substituent and the other Ph group on the ligand

(top-left quadrant) causes the structure to distort from its ideal,

chair-shaped cyclic geometry. Finally, a minor diastereomer

can form if, relative to the favored transition state, the opposite

face of the aldehyde is attacked (Figure 3, right panel). The

dominant destabilizing interaction in this case is between the

aldehyde substituent and the Ph group of Ph-BPE in the top-left

quadrant. Overall, this model determines the correct sense of

selectivity, although the magnitude is somewhat overestimated

relative to experiment (95:5 er, 5:1 dr).

We also performed kinetic experiments to further explore

the effect of slow addition on the chemoselectivity of our reac-

tion (Figure 4). Under the standard conditions, except with no

diene present, the reduction of aldehydes is extremely rapid. In

our experiment, benzaldehyde was fully consumed within 40

min, forming the silyl-protected benzyl alcohol (Figure 4, top

panel). If a single equivalent of diene is added at the beginning

of the reaction, the corresponding reductive coupling product is

observed to form in a roughly 1:9 ratio with the reduction prod-

uct (Figure 4, middle panel). Notably, however, the overall con-

sumption of starting material has been retarded, with the reac-

tion now requiring over 3 h to reach full consumption of starting

material. Finally, when a large excess of diene is added at the

beginning of the reaction (5.0 equiv diene, Figure 4, bottom

panel), the reductive coupling product is observed to form at a

higher ratio relative to the reduction product. Simultaneously,

the total consumption of starting material is further retarded.

Two conclusions can be drawn from these data. First, the

correlation of the product-to-reduction ratio with the diene-to-

aldehyde concentration ratio supports the proposed the role of

slow addition in our mechanistic scheme. In Figure 2, higher

concentration of diene lowers the energy of the blue pathway

relative to the red pathway, and therefore leads to increased for-

mation of the coupling product. Second, the seemingly inhibi-

tory effect of the diene explains why the slow addition protocol

must be conducted over a relatively long timespan (~3.5 h), in

spite of the fact that we are trying to outcompete an extremely

rapid reaction (half-life on the order of several min). Under the

conditions of our protocol, at large excesses of diene relative to

aldehyde, the rate of both the reduction and desired coupling

are slow.

■ CONCLUSION

In summary, we have developed a highly efficient copper-

catalyzed allylation of aldehydes using dienes as allylmetal sur-

rogates. Computational studies were performed which indicate

that a reversible isomerization of copper(I) allyl species is

formed, from which reaction of the trans-linear isomer with the

aldehyde yields the major stereoisomer of product. Transition

state models are provided, which show the specific steric inter-

actions between ligand and substrates that are responsible for

the stereoselectivity. Finally, kinetic experiments were per-

formed, demonstrating effect of aldehyde–diene relative con-

centration on the chemoselectivity of this reaction.

(15) In general, away from equilibrium, the Gibbs free energy

of reaction ∆G differs from the standard free energy of reaction

∆G‡ by a quantity related to the reaction quotient Q:

∆G – ∆G‡ = RT ln Q

In our system of interest, the aldehyde concentration is presum-

ably maintained at a very low value, meaning that states involv-

ing free aldehyde are lowered in free energy relative to those

involving the aldehyde bound to the catalyst. Although this ef-

fect is not reflected in Figure 2, which shows only the standard

free energies, it is a useful mnemonic to associate the effect of

decreasing the steady-state aldehyde concentration with raising

the energies of the grey-highlighted states relative to the white

ones.

I. General Information.

General reagent information. All reactions were performed under a nitrogen

atmosphere using the indicated method in the general procedures. Toluene and

tetrahydrofuran (THF) were purchased from J.T. Baker in CYCLE-TAINER® solvent

delivery kegs and purified by passage under argon pressure through two packed columns

of neutral alumina and copper(II) oxide. Copper(II) acetate was purchased from Strem

and used as received. 1,2-bis((2S,5S)2,5-diphenylphospholano)ethane ((S,S)-Ph-BPE) and

1,2-bis((2R,5R)2,5-diphenylphospholano)ethane ((R,R)-Ph-BPE) ligands were purchased

from Namena Corp. and stored in a nitrogen-filled glove box. JosiPhos ligand (R)-1-

{(SP)-2-[Bis[4-(trifluoromethyl)-phenyl]phosphino]ferrocenyl}ethyldi-tert-

butylphosphine (JosiPhos SL-J011-1) was a gift from Solvias and stored in a nitrogen-

filled glove box. (R)-DTBM-SEGPHOS was purchased from Takasago. (S,S)-QuinoxP*

was donated by Nippon Chemical Industrial Co., Ltd. and stored in a nitrogen-filled

glove box. Dimethoxy(methyl)silane (DMMS) was purchased from Tokyo Chemical

Industry Co. (TCI) and stored in a nitrogen-filled glove box for long term storage.

(Caution: Dimethoxy(methyl)silane (DMMS, CAS: 16881-77-9) is listed by several

vendors (TCI, Alfa Aesar) SDS or MSDS as H318, a category I Causes Serious Eye

Damage. Other vendors (Sigma-Aldrich, Gelest) list DMMS as H319, a category II Eye

Irritant. DMMS should be handled in a well-ventilated fumehood using proper

precaution as outlined for the handling of hazardous materials in prudent practices in the

laboratory.1 At the end of the reaction, ammonium fluoride in methanol should be

carefully added to the reaction mixture. The resulting reaction mixture should be stirred

for at least 30 min or the time indicated in the detailed reaction procedure. All other

solvents and commercial reagents were used as received from Alfa Aesar, Acros

Organics, Chem-Impex, Combi-blocks, Sigma-Aldrich, Strem or TCI, unless otherwise

noted. Flash column chromatography was performed using 40-63 µm silica gel

(SiliaFlash® F60 from Silicycle), or with the aid of a Biotage Isolera Automated Flash

Chromatography System using prepacked SNAP silica cartridges (10-100 g). Organic

solutions were concentrated under reduced pressure using a Buchi rotary evaporator.

General analytical information. All new compounds were characterized by NMR

spectroscopy, IR spectroscopy, elemental analysis or high-resolution mass spectrometry,

optical rotation (if applicable), and melting point analysis (if solids). 1H, 13C, 19F and 31P

NMR spectra were recorded in CDCl3 or C6D6 on a Bruker 400 or 500 MHz instrument.

Chemical shifts for 1H NMR are reported as follows: chemical shift in reference to

residual CHCl3 at 7.26 ppm (δ ppm), multiplicity (s = singlet, br s = broad singlet, d =

doublet, t = triplet, q = quartet, sex = sextet, sep = septet, ddd = doublet of double of

doublets, td = triplet of doublets, m = multiplet), coupling constant (Hz), and integration.

Chemical shifts for 13C NMR are reported in terms of chemical shift in reference to the

CDCl3 solvent signal (77.16 ppm). IR spectra were recorded on a Thermo Scientific

Nicolet iS5 spectrometer (iD5 ATR, diamond) and are reported in terms of frequency

of absorption (cm-1). Melting points were measured on a Mel-Temp capillary melting

point apparatus. Optical rotations were measured using a Jasco P-1010 digital polarimeter.

Elemental analyses were performed by Atlantic Microlabs Inc., Norcross, GA. High-

resolution mass spectra were recorded on a JEOL AccuTOF LC-Plus 46 DART system

and on an Agilent Technologies 6545 Q-TOF LC/MS system. Achiral gas

chromatography (GC) analyses were performed on an Agilent 7890A gas chromatograph

with an FID detector using a J & W DB-1 column (10 m, 0.1 mm I.D.). Enantiomeric

ratios (er’s) were determined by chiral SFC analysis using a Waters Acquity UPC2

instrument, Agilent 1200 Series HPLC (high performance liquid chromatography) or

Agilent 7890A GC analysis using a chiral stationary phase. Specific columns and

analytical methods are provided in the experimental details for individual compounds; the

wavelengths of light used for chiral analyses are provided with the associated

chromatograms. Thin-layer chromatography (TLC) was performed on silica gel 60Å F254

plates (SiliaPlate from Silicycle) and visualized with UV light or potassium

permanganate stain. Preparatory thin-layer chromatography (Prep-TLC) was performed

on silica gel GF with UV 254 (20 x 20 cm, 1000 microns, catalog # TLG-R10011B-341

from Silicycle) and visualized with UV light. The syringe pumps (PHD 2000 and PHD

Ultra) were purchased from Harvard Apparatus. Isolated yields reported in Table 2 of the

manuscript reflect the average values from two independent runs.

- Step 1 (Synthesis of enol phosphate S3’)

An oven-dried 500 mL round bottom flask equipped with a magnetic stir bar was

evacuated and backfilled with argon. The flask was then charged with 3'-

fluoroacetophenone (6.1 mL, 50 mmol, 1.0 equiv) and anhydrous THF (180 mL). The

solution was cooled to -78 °C and LiHMDS (1.0 M in THF, 65 mL, 65 mmol, 1.3 equiv)

was added dropwise over 50 min via syringe pump. The resulting solution was allowed to

stir at -78 °C for 30 min. Diethyl chlorophosphate (10.9 mL, 75 mmol, 1.5 equiv) was

then added dropwise over 20 min via syringe pump and the reaction mixture was further

stirred at -78 °C for 3 h. The reaction mixture was allowed to warm to room temperature

and was quenched with sat. NH4Cl solution. The resulting mixture was transferred to a

separatory funnel and extracted with EtOAc (70 mL x 3). The combined organic layers

were dried over MgSO4, filtered, and concentrated under reduced pressure. The crude

product was purified by silica gel column chromatography (EtOAc/hexanes = 100/0 to

50/50) to afford the desired enol phosphate S3’ as an orange oil (7.5 g, 55% yield). 1H

III. General Procedure for CuH-Catalyzed Aldehyde Allylation

Reactions.

In a nitrogen-filled glovebox, an oven-dried screw-cap reaction tube (Fisherbrand, 20 x

150 mm, catalog no. 1495937C) equipped with a stir bar was charged with Cu(OAc)2 (1.8

mg, 0.01 mmol, 1.0 mol %) and (S,S)-Ph-BPE (6.1 mg, 0.012 mmol, 1.2 mol %),

followed the addition of toluene (0.2 mL) via syringe (Note: addition of the exact amount

of copper catalyst and ligand is crucial for reaction efficiency). The reaction mixture was

stirred at room temperature for 3 min before the addition of the diene (2.0 mmol, 2.0

equiv) and DMMS (490 L, 4.0 mmol, 4.0 equiv), sequentially, via syringe. The reaction

vessel was capped (Cap: Kimble Chase Open Top S/T Closure catalog no. 73804-15425;

Septum: Thermo Scientific 1.3 mm silicone/PTFE catalog no. B7995-18) and removed

from the glovebox. The cap was wrapped in parafilm and the reaction tube was then

placed in an ice/water bath at 0 °C and stirring was commenced (Note: When R2 =

cyclohexyl or adamantyl, The reaction mixture was stirred at room temperature for 30

min before being placed in an ice/water bath at 0 °C). A stock solution of aldehyde was

prepared in a glovebox by dissolving 2.0 mmol of aldehyde in ca. 2 mL of toluene (1.0 M,

2 mL volumetric flask was used to prepare the stock solution, see Figure S1) Then, 1.0

mL of this aldehyde stock solution (1.0 mmol, 1.0 equiv) was slowly added to the

reaction vessel via syringe pump (addition rate - 5 μL/min). The resulting reaction

mixture was stirred at 0 °C (Note: the reaction temperature should be maintained at 0 °C

until the addition of the aldehyde is completed) and allowed to slowly warm to room

temperature overnight (18 h). After the reaction was completed as judged by GC-MS, a

saturated solution of NH4F in MeOH (ca. 10 mL) was carefully added to quench the

reaction (Caution: gas evolution was observed). The mixture was allowed to stir for 30

min at room temperature, diluted with EtOAc (ca. 15 mL), stirred for an additional 20

min at room temperature and then filtered through a short plug of Celite (2.0 cm) eluting

with additional EtOAc (ca. 20 mL). The solvent was removed under reduced pressure

with the aid of a rotary evaporator. At this point, the combined yield (of the

diastereomers) and the diastereomeric ratio (dr) were determined by 1H NMR

spectroscopic analysis using dibromomethane or 1,1,2,2-tetrachloroethane as an internal

standard (Note: The dr was determined by 1H NMR of the purified compound when it was

unable to be determined by 1H NMR of the unpurified reaction mixture due to the

complexity of the spectrum). The crude reaction mixture was purified by flash column

chromatography with the aid of a Biotage Isolera instrument to afford the desired product.

Enantiomeric ratios (er’s) were determined by chiral SFC analysis using a Waters

Acquity UPC2 instrument or HPLC or GC analysis using a chiral stationary phase.

VII. General Procedure for Kinetics Experiments

In a nitrogen-filled glovebox, five oven-dried screw-cap reaction tubes (Fisherbrand, 20 x

150 mm, catalog no. 1495937C), each equipped with stir bars, were charged with

Cu(OAc)2 (1.8 mg, 0.01 mmol, 2.0 mol %) and (S,S)-Ph-BPE (5.1 mg, 0.01 mmol, 2.0

mol %), followed the addition of dry toluene (0.2 mL) via syringe. After the reaction

mixtures were stirred at room temperature for 3 min, the diene (indicated equiv) and

DMMS (245 μL, 2.0 mmol, 4.0 equiv) were added to each tube via syringe. The reaction

vessels were capped (Cap: Kimble Chase Open Top S/T Closure catalog no. 73804-

15425; Septum: Thermo Scientific 1.3 mm silicone/PTFE catalog no. B7995-18) and

removed from the glovebox. The caps were wrapped in parafilm and the reaction tubes

were then placed in a rt water bath and stirred. Benzaldehyde (51 μL, 0.5 mmol, 1.0 equiv)

was added to each tube quickly via a glass microsyringe, and a timer was started. After

the indicated time, according to the quenching schedule shown below, a saturated

solution of NH4F in MeOH (ca. 5 mL) was carefully added to quench one of the reactions

(Caution: gas evolution was observed). The mixture was allowed to stir for 30 min at

room temperature, diluted with EtOAc (ca. 10 mL), stirred for an additional 20 min at

room temperature and then filtered through a short plug of Celite (2.0 cm) eluting with

additional EtOAc (ca. 10 mL). The solvent was removed under reduced pressure with the

aid of a rotary evaporator. At this point, the reaction mixture was analyzed by 1H NMR

spectroscopic analysis using 1,1,2,2-tetrachloroethane as an internal standard. The yield

of product represents the combined yield of the two diastereomers, which were formed

with roughly 5:1 dr.

VIII. Computational Studies

Computational Details. All reported calculations were performed using the ORCA

software5 or GAUSSIAN 036. Images of the 3D structures were rendered using

CYLView.7 The geometry of all reactants and transition states were optimized using the

B3LYP functional in the gas phase. In these geometry optimizations, a mixed basis set of

SDD for Cu and 6-31G(d) for all other atoms was used. Ground and transition state

geometries were validated by vibrational analysis at the same level, showing zero and one

imaginary frequencies respectively. Single point energies were calculated using the M06-

2X8,9 functional on a mixed basis set of SDD for Cu and 6-311+G(d,p) for all other atoms.

In these energy calculations, the SMD solvation model10 with toluene as solvent was

applied. The reported Gibbs free energies and enthalpies include zero-point and thermal

corrections calculated at 298 K using B3LYP/SDD–6-31G(d).
