Abstract

The present invention pertains to a method for producing an optically active compound which includes a step for reducing an imino group of an imine compound or a step for reducing an unsaturated bond of a heterocyclic compound, while in the presence of hydrogen gas as a hydrogen donor and one or more types of complexes selected from a group consisting of a complex represented by general formula (1), a complex represented by general formula (2), a complex represented by general formula (3), and a complex represented by general formula (4) (the general formulas (1)-(4) are as stipulated by claim).
