Abstract

A general method for the stereoselective coupling of unprotected oligosaccharides with any substrate containing a N, O-disubstituted hydroxylamine group is described. The cyclic nature of the oligosaccharide reducing unit is preserved and the substrate glycosylated with high diastereoselectivity to sugar through an amino (N [OR2]-) or an aminoxy (N [R1]-O-) linkage. Due to the uniquely high chemical reactivity and specificity of disubstituted ...
