Deprotection of acetylated glycoside in the presence of catalytic amounts of dibutyltin oxide in methanol was described. Acetyl groups in these glycosides could be smoothly and selectively deprotected in good yields without obvious isomerizations or degradations of the sugar part under the reaction conditions. Compared to the previous methods, this new method has the advantages of simple procedure, mild condi-tions and high yields.

Key words: deacetylation, dibutyltin oxide, regioselectivity, aliphatic glycoside
