A process for producing an optically active .beta.-hydroxyketone represented by formula (I): ##STR1## by catalytic asymmetrical aldol reaction is disclosed, comprising reacting a silyl-enol ether represented by formula (II): ##STR2## with a substituted aldehyde represented by formula (III): R.sup.5 CHO (III) in the presence of a binaphthol-titanium complex represented by formula (IV): ##STR3## An optically active .beta.-hydroxyketone is efficiently produced with diastereo-specificity and enantio-specificity.
