Glycosylation reactions using
N-benzyl-2,3-
trans-oxazolidinones as the glycosyl donors were shown to be highly
-selective. Advantages of the donor include facile preparation in gram-scale preparation and simple deprotection procedures. Subsequently, a one-pot oligosaccharide synthesis involving 1,2-
cis glycosidic linkages was demonstrated using the novel glycosyl donors.
