摘要
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 corresponding epoxides obtained were nearly optically pure. © 1990.
