Abstract: Treatment of tri-O-acetyl-d-glucal 1 with several alcohols in the presence of catalytic amount of POM (K(5)CoW(12)O(40).3H(2)O) as a heterogeneous, reusable, efficient and environmentally benign catalyst under neutral conditions and ambient temperature gave the corresponding 2,3-unsaturated glycopyranosides in excellent yields, with good anomeric selectivity. This catalyst proved to be not efficient for phenols.
