Asymmetric epoxidation of a,b-unsaturated ketones with H2O2 was developed using a chiral quaternary ammonium salt as the phase-transfer catalyst. A catalytic amount of N-[4-(iodo)benzyl]cinchoninium bromide, easily prepared from cinchonine, was effective in the asymmetric epoxidation for producing the corresponding desired products with up to 92% ee under mild reaction conditions.

Enantioselective Darzens condensation has been achieved from optically active ortho substituted benzaldehyde(tricarbonyl)chromium complexes. The enantiomeric excesses were very high with 2-methoxy and 2-chloro benzaldehyde(tricarbonyl)chromium and the cor
