A Novel and Efficient Deprotection of the Allyl Group at the Anomeric Oxygen of Carbohydrates

Abstract
Perfluoroalkylation with perfluoroalkyl iodide under sodium dithionite and sodium bicarbonate in acetonitrile/water followed by elimination in the presence of zinc powder and ammonium chloride in ethanol was disclosed to be an extremely mild and efficient procedure for deprotection of the anomeric allyl group of carbohydrates.
