PROCESS FOR PRODUCTION OF OPTICALLY ACTIVE COMPOSITIONS BY UTILIZING OPTICALLY ACTIVE AMIN-BORON COMPOSITIONS |
摘要 |
Optically active hydroxybenzylamine derivatives of the Formula: <CHEM> wherein R<1> denotes a hydrogen atom, lower alkyl group or lower alkoxy group; R<2> 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. |
