an effort to prepare complex oligosaccharide derivatives, a series of unexpected a glycosides were predominantly formed in the presence of neighboringgroupparticipation using imidates or thioglycosides as glycosyl donors under standard glycosylation conditions. The observations are especially suitable in the case of alpha-(1-->3) glycosidic bond formation. (C) 2002 Elsevier Science Ltd. All rights
