Patent ID: 7164026

Claim:
A polymer-carrying optically active binaphthyl oxazoline compound having axial asymmetry, represented by formula (1): wherein: R 1 and R 2 independently represent a hydrogen atom, an alkyl group having from 1 to 6 carbon atoms, or an aryl group which may have a substituent or a benzyl group which may have a substituent; R 3 represents a hydrogen atom or —R 5 —X—R 6 ; R 4 represents a hydrogen atom, an alkyl group having from 1 to 4 carbon atoms or a tri(C 1-4 alkyl)silyl group; R 5 represents a straight- or branched-chain aliphatic hydrocarbon chain which may have a directly or indirectly bonded substituent; X represents CH 2 , CO 2 , O, CONR 7 or NR 7 ; R 6 represents a directly or indirectly bonded polymer; and R 7 represents a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms.
