摘要: A process for preparing an optically active carboxylic acid is disclosed, comprising asymmetric hydrogenation of an .alpha.,.beta.-unsaturated carboxylic acid using an alcohol as a hydrogen donor in the presence of a metal-optically active phosphine complex. A carboxylic acid having high optical purity can easily be obtained in a high yield without using specific equipment as required in using hydrogen gas as a hydrogen donor.
