Abstract
The invention provides a method for preparing an optically active alcohol comprising the step of reacting a ketone compound with a hydride reagent in the presence of an optically active metal compound. The resulting optically active alcohols are useful as intermediates for the synthesis of physiologically active compounds such as drugs and pesticides, functional materials such as liquid crystals, and raw materials for synthesis in fine chemistry. A novel optically active cobalt (II) complex useful as a catalyst is also provided.
