Abstract

Provided herein is an optically active alcohol having a silyl group, stannyl group, or halogen atom at the .gamma.-position, selected from compounds represented by the general formula [I], ##STR1## the general formula [II], ##STR2## the general formula [III], ##STR3## and the general formula [IV], ##STR4## (where, R denotes a C.sub.1 -C.sub.10 substituted or unsubstituted alkyl group or substituted or unsubstituted phenyl group; A denotes a silyl group represented by ##STR5## a stannyl group represented by ##STR6## or a halogen atom. R.sup.1, R.sup.2, and R.sup.3 are substituted or unsubstituted C.sub.1 -C.sub.10 alkyl groups or substituted or unsubstituted phenyl group, which may be the same or different, provided that this does not apply in the case where A represents a stannyl group or halogen atom in the general formulas [III] and [IV].); a process for producing the same, and a process for resolving the optically active alcohol into isomers of high optical purity.
