Modified Cinchona Alkaloid―Zinc Complex Catalysts: Enantioselective Monoacetylation of Glycerol Derivatives with Acetic Anhydride

Enantioselective monoacetylation of σ-symmetric glycerol derivatives with acetic anhydride catalyzed by modified cinchona alkaloid―zinc complexes was achieved in up to 86% ee at 5 mol% catalyst loading.
