    摘要: A process is provided for efficiently producing an optically active 3-quinuclidinol derivative of high optical purity using a readily available ruthenium compound as an asymmetric reduction catalyst. This process is a process for producing an optically active 3-quinuclidinol derivative represented by the following formula (III) comprising asymmetrically hydrogenating a 3-quinuclidinone derivative represented by the following formula (I) in the presence of a ruthenium compound (II) represented by formula (II): Ru(X)(Y)(Px)n[R1R2C*(NR3R4)-A-R5R6C*(NR7R8)] (in the formulas, R represents a hydrogen atom or C7 to C18 aralkyl group and the like, X and Y represent hydrogen atoms or halogen atoms and the like, Px represents a phosphine ligand, n represents 1 or 2, R1 to R8 represent hydrogen atoms or C1 to C20 alkyl groups and the like, * represents an optically active carbon atom and A represents an ethylene group and the like).
