摘要：
A new poly(ethylene glycol)-supported multiple hydrogen bond catalyst has been prepared and its ability as a promoter in asymmetric transfer hydrogenation of beta-acylamino nitroolefins has been studied. The PEG-supported multiple hydrogen bond catalyst exhibits high enantioselective manner (ee up to 95%) and it is easily removable by selective precipitation with diethyl ether and filtration from the reaction mixture, the polymer-bound catalyst has been recycled up to six times no loss of chemical and stereochemical efficiency.
