An Efficient and Regioselective Deprotection Method for Acetylated Glycosides

Abstract

A new regioselective 2-O-deacetylation methodology of acetylated glycosides using 85% hydrazine hydrate in THF is described. Using this method, acetylated 1-thio-glycoside could also be selectively deprotected to give 3-O-deprotected compound.
