Glycosyl phosphates have emerged as useful glycosyl donors for stereoselective glycosidic bond formation in the synthe- sis of oligosaccharides. In this account, we describe some of our work in developing and further expanding this methodology, partic- ularly with the use of propane-1,3-diyl phosphate as the anomeric leaving group. We have studied the reactions of several glycosyl propane-1,3-diyl phosphates with or without C-2 participating groups with a range of glycosyl acceptors in the presence of trime- thylsilyl triflate in either stoichiometric or catalytic amount, and demonstrated their application in the synthesis of several disaccha- rides and also the synthesis of some trisaccharides.
