METHOD FOR PRODUCING OPTICALLY ACTIVE CYCLOPROPANE CARBOXYLIC ACID ESTER COMPOUND, ASYMMETRIC COPPER COMPLEX, AND OPTICALLY ACTIVE SALICYLIDENEAMINOALCOHOL COMPOUND

摘要

A process for producing an optically active cyclopropanecarboxylic acid ester compound represented by the formula (4): (wherein R 5 , R 6 and * each represents the same meaning as defined below), comprising reacting a diazoacetic acid ester represented by the formula (2): €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒN 2 CHCO 2 R 5 €ƒ€ƒ€ƒ€ƒ€ƒ(2) (wherein R 5 represents an alkyl group having 1 to 15 carbon atoms or the like) with a compound represented by the formula (3): (wherein R 6 represents an alkyl group having 1 to 15 carbon atoms or the like), in the presence of an asymmetric copper complex obtained by reacting a copper compound and an optically active salicylideneaminoalcohol compound represented by the formula (1) : (wherein R 1 represents an alkyl group having 1 to 4 carbon atoms or the like, R 2 represents a hydrogen atom or the like, R 3 and R 4 independently represent a hydrogen atom or the like, and * represents an asymmetric center).
