摘要：

Cheap 4 Angstrom molecular sieves can promote acetylation of carbohydrate hydroxyl functions with Ac2O in absence of any co-reagent. The procedure is compatible with the presence of a variety of acid labile protecting groups and can be exploited for regioselective protections. (C) 2003 Elsevier Science Ltd. All rights reserved.
