Dialkylphosphates as stereodirecting protecting groups in oligosaccharide synthesis

(Chemical Equation Presented) Double duty: A phosphoric ester at the C2 position in glycosyl donors directs the glycosylation to occur selectively at the anomeric carbon atom with complete 1,2-trans selectivity. Since the phosphoric ester can be removed to give the hydroxy function, this group serves as a stereodirecting protecting group in oligosaccharide synthesis.
