New Schiff base chiral polymers was synthesized. The asymmetric addition of diethyl zinc to aldehyde was achieved catalyzed by Ti(Ⅳ)polymer which was formed in situ from chiral polymer and Ti(O-i-Pr)4. Optical alcohols were obtained in a high yield with e.e. up to 84.5%. The effects of temperature, complex time, structure of substrate etc. on the catalytic activity and enantio selectivity were studied in detail. The reaction mechanism was proposed.
