Optically active hydroxybenzylamine derivatives of the Formula:
wherein R¹ denotes a hydrogen atom, lower alkyl group or lower alkoxy group; R² denotes a lower alkyl group; * signifies an asymmetric carbon atom; and the hydroxyl group is located on the phenyl at the ortho- or meta- position relative to the substituent having the asymmetric carbon,
an optically active amine-boron compound having said derivative as a ligand, and
a process for producing an optically active compound by using said compound.
The derivations are useful as asymmetric ligands of asymmetric reducing agents. The optically-active amine-boron complex enables optically active products to be obtained specifically.
