Furan derivativesR 0060 Manganese(III) Acetate Based Oxidative Cyclizations of 3-Oxopropanenitriles

with Conjugated Alkenes and Synthesis of 4,5-Dihydrofuran-3-carbonitriles Con-taining Heterocycles. — Oxidative cyclizations of oxopropanenitriles with diphenyl-alkenes or phenyl(thienyl)alkenes are comparatively studied. As a result, the thienyl--substituted alkenes afford higher yields of title furancarbonitriles than diphenylalkenes (II) and (IV). — (YILMAZ*, M.; UZUNALIOGLU, N.; PEKEL, A.
