摘要：

Acetic anhydride-pyridine over basic alumina has been used in order to carry out acetylations of hydroxy, thiol and amino groups in solvent-free conditions under microwave irradiation. The technique can be extended for selective acetylations by regulation of irradiation time. (C) 2002 Elsevier Science Ltd. All rights reserved.
