AN EFFICIENT CONSTRUCTION OF 1, 2-TRANS-β-GLYCOSIDIC LINKAGES VIA BENZYL-PROTECTED GLYCOPYRANOSYL P, P-DIPHENYL-N-(p-TOLUENESULFONYL)-PHOSPHINIMIDATES

An efficient 1, 2-trans-glycosidation reaction withon neighbouring group participation has been developed using benzyl-protected P, P-diphenyl-N-(p-toluensulfonyl)phosphinimidates as glycosyl donors in the presence of trimethylsilyl triflate or boron trifluoride etherate.
