ABSTRACT:
A process for preparing an optically active alcohol by reacting a prochiral ketone corresponding to the optically active alcohol and an acid with a mixture of (1) a boron-containing compound selected from the group consisting of i) a borane compound which is obtained from an optically active .beta.-aminoalcohol and a boron hydride; or obtained from the optically active .beta.-aminoalcohol, a metal borohydride and an acid and ii) an optically active oxazaborolidine and (2) a metal borohydride; and a process for preparing an optically active amine by reacting an oxime derivative and an acid with a mixture of (1) a boron-containing compound selected from the group consisting of i) a borane compound which is obtained from an optically active .beta.-aminoalcohol and a boron hydride, or obtained from said optically active .beta.-aminoalcohol, a metal borohydride and an acid and ii) an optically active oxazaborolidine, and (2) a metal borohydride.
