摘要
Covalent immobilization of (1R,2S)-(-)-ephedrine, used as a model molecule of beta-aminoalcohols, on the surface of MCM-41-type mesoporous aluminosilicates, performed by a new sol-gel method, leads to chiral auxiliaries which show greatly enhanced rates and ee's compared to those reported up to now in the enantioselective addition of diethylzinc to benzaldehyde.
