摘要：

A polymer(fiber)-supported chiral amino alcohol was synthesized and applied to the enantioselective addition of diethylzinc to benzaldehyde. Compared with the resin-supported chiral amino alcohol in the same reactive time, the fiber-supported amino alcohol could increase the yield and ee value by 34% and 9% respectively. This fiber-supported catalyst could be recycled more than 5 times. The reason why catalytic property was dropped down in recycle was proved to be the loss of catalyst by the analysis of their SEM photographs.
