Abstract

N-(p-methylstyryl)-(1R,2S)-ephedrine is prepared by alkylation of p-chloromethylstyrene under conditions which do not favor quaternization. A series of Copolymerization reactions confirm that the new chiral monomer and styrene copolymerize in random fashion with r1=1.09 and r2=0.98. The optical rotation of the copolymers does not vary linearly with composition. Applications of the copolymer include its use as chiral ligand for asymmetric synthesis or as a separation medium.
