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.
本发明的目的是解决先前技术中的问题,并找到更改进的反应条件,以抑制产物的消旋化并获得高光学纯度的光学活性醇。发明者通过使用一种能够分离不对称催化剂和甲酸盐的溶剂系统,使氢源和不对称催化剂能够存在于同一相中,从而解决了上述问题。
