The object of this invention is to provide a method for producing an optically active secondary alcohol at a high optical purity by hydrogenating a substrate carbonyl compound at a high efficiency using as a catalyst a ruthenium complex bearing as a ligand certain optically active diphosphine compound and a readily synthesized amine compound.
The method of producing an optically active secondary alcohol according to the present invention is characterized in that a substrate carbonyl compound (provided that 3-quinuclidinone, 3-quinuclidinone derivative having a substituent, and a ketone having an aromatic hydrocarbon group and a heterocycle are excluded) is reacted with hydrogen and/or a hydrogen donating compound in the presence of a ruthenium complex selected from the compounds expressed by following general formula (1) RuXYAB (1) [in the general formula (1), X and Y are the same or different from each other and denote a hydrogen atom or an anionic group, A denotes an optically active diphosphine expressed by the general formula (2), B denotes an amine compound expressed by following general formula (3)].
