摘要：

A highly stereocontrolled 1,2-trans-beta-glycosidation reaction with or without neighbouring group participation has been developed by using benzyl- or benzoyl-protected glycopyranosyl N,N,N',N'-tetramethylphosphoroamidates as shelf-stable glycosyl donors in the presence of trimethylsilyl trifluoromethanesulfonate or boron trifluoride etherate. Several notable features of the present method not observed with the diphenyl phosphate method are also described.
