HydroxylationO 0216 Iron-Catalyzed Asymmetric Olefin cis-Dihydroxylation with 97% Enantiomeric

Excess. — Several bis(2-pyridylmethyl)-1,2-bipyrrolidine ligands are prepared by lit-erature processes and their iron(II) complexes investigated in the cis-dihydroxylation of olefins. For the first time, a synthetic nonheme iron catalyst shows enantioselectiv-ities comparable with those obtained with the osmium-based AD mixes. — (SUZUKI, K.; OLDENBURG, P. D.; QUE*, L. J.; Angew.
