Abstract
A catalytic enantioselective 1,2-reduction of enones with potassium borohydride is catalyzed by a chiral N,N'-dioxide-Sc(III) complex catalyst under mild reaction conditions. A number of optically active allylic alcohols were obtained in very good enantioselectivities with nearly quantitative yields.
