Abstract
A novel copolymer containing chiral epoxy residues was prepared. Free radical initiated suspension copolymerization of ( R)- or ( S)-glycidyl methacrylate with ethylene glycol dimethacrylate afforded crosslinked copolymer 1 in high yield. Optically active polymers containing amino alcohol functionalities were then formed from 1 through epoxide ring opening with a number of achiral and homochiral amines. It was shown that ruthenium complexes based on these new polymeric amino alcohol ligands were effective catalysts for the asymmetric hydrogen transfer reduction of acetophenone.
