title: One-pot acetalation-acetylation of sugar derivatives employing perchloric acid immobilised on silica.
abstract: Perchloric acid immobilised on silica gel has been used as an efficient promoter for per-O-acetylation, and acetalation and subsequent O-acetylation of glycosides and thioglycosides in one-pot using stoichiometric reagents.
