We have demonstrated that quaternary ammonium salts of cinchona alkaloids grafted to a poly(ethylene glycol) matrix are efficient homogeneous catalysts in the enantioselective alkylation of glycine Schiff base derivatives. The role of the solvent, the molecular weight of the polymer and the anchorag
