摘要：
The object of the present invention is to solve the problems in the prior arts, and to find more improved reaction conditions for suppressing the racemization of the product and obtaining an optically active alcohol at a high optical purity. The inventors achieved to solve the above problems by using a solvent system that is capable of resolving both an asymmetric catalyst and a formate salt, allowing the hydrogen source and the asymmetric catalyst to be present in the same phase.
