Process for preparing an optically active amine

摘要

A novel process for preparing an optically active amine by asymmetric hydrogenation of an imine compound, such as an imine compound prepared by condensing benzylamine and acetophenone, in the presence of a catalytic amount of an iridium-optically active phosphine complex and benzylamine or a benzylamine derivative. The present invention provides an optically active amine of high optical purity.
