Abstract:	The acetyl group was chemoselectively cleaved in the presence of p-toluenesulfonic acid (p-TsOH) in CH2Cl2/MeOH without affecting the benzoyl (benzoate and p-bromobenzoate) groups and no transesterification product was observed. The treatment of protected carbohydrates with p-TsOH·H2O at room temperature usually required a longer reaction time than at 40°C. Other types of sulfonic acid such as 10-camphorsulfonic (CSA) led to similar results.
