HALOGENATED INDENONES AND METHOD FOR PRODUCING OPTICALLY ACTIVE INDANONES OR OPTICALLY ACTIVE INDANOLS BY USING SAME

摘要

An optically active ketone represented by formula (2) (wherein Ar1 represents a furyl group, a thienyl group, or a C6-20 aryl group; X1 represents a halogen atom; and * represents an asymmetric point) is produced by stereoselectively reducing an enone compound represented by formula (1) (wherein Ar1 and X1 are the same as the above).
