ABSTRACT:
The optically active benzylamine derivatives of the present invention are very useful for use as the asymmetric ligand of an asymmetric reducing agent. By using the optically active amine-boron complex prepared from the compound of the present invention, optically active products can be obtained in a specifically high optical yield. Moreover, the separation and recovery of the reaction products and asymmetric ligand can be easily achieved.
