2,3,6,3',4'-Penta-O-acetylsucrose(6-PAS) was synthesized from sucrose via tritylation, acetylation, detritylation and acetyl migration.An effective reagent protecting the hydroxyls of sucrose was used to improve the yield of the reaction.In the process of protecting, the effects of reaction temperature and reaction time were studied.The two steps of detritylation and acetyl migration were analyzed by HPLC to chose the better route.The products were characterized by means of ¹H NMR and IR.The result shows that the optimum conditions for protecting hydroxyl are:tritylation at 50℃ for 4 h and acetylation at 105℃ for 3 h.The yield is 81.9%.
