Several monosaccharides were peracetylated in excellent isolated yields (89-100%) with vinyl acetate in aqueous Na 3 PO 4 . The per-O-acetylation reaction is fast and mild, as well as insensitive to water. Meanwhile, the workup is convenient and the catalyst can be recycled easily.
Vinyl acetate and sodium carbonate catalysed acetylation of several monosaccharides is an efficient synthesis of per-O-acetylation of carbohydrates and achieve the products in excellent yields and short reaction times. d-Glucose as the substrate in large scale also proceeds in high yield.
