Abstract:


The regioselective 1-O-deacetylation of peracetylated carbohydrates with ammonium acetate in DMF (or a mixed solution of tetrahydrofuran and methanol) is described. It offers a facile and efficient way to prepare O-acetylpyranosides presenting one free hydroxyl group at the anomeric position.

Keywords:

Carbohydrates, regioselectivity, glycosides, acylation, glycosylations
