Glycosyl donors having a diphenylphosphinate and a propane-1,3-diyl phosphate leaving group were easily prepared by the addition of the anomeric hydroxyl group of 2,3,4,6-tetra-O-benzyl-α,β-D-glucopyranose to diphenylphosphinic and propane-1,3- diyldioxyphosphoryl chlorides. These glycosyl donors were selectively glycosylated with a number of primary and secondary oxygen nucleophiles in the presence of trimethylsilyl triflate (TMSOTf). The use of 1,3-diyl phosphate resulted in the stereoselective formation of β-O-linked glycosides.

The O-benzylated α- and β-glucosyl trichloroacetimidates 1a-α and 1a-β afforded with the phosphinic acid derivative 2 and the phosphonic acid derivative 3 directly the corresponding O-glucosylated products 4 and 5, resp., with inversion at the anomeric ce
