摘要

A novel stereoselective synthesis of (-)-beta-conhydrine is achieved. Stereoselective Grignard reaction of (R)-2,3-O-cyclohexylidine glyceraldehyde with ethyl magnesium bromide, chelation controlled stereoselective Grignard reaction of allyl imine derivative with allyl magnesium bromide, and ring-closing metathesis (RCM) of the diallyl product provides (-)-beta-conhydrine in high yield.
