摘要

Abstract A highly stereocontrolled 1, 2-trans-β-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 ...
