Preparation of orthogonally protected chitosan oligosaccharides: observation of an anomalous remote substituent effect.

Orthogonally protected chitosan tetrasaccharides were synthesized in a convergent fashion by trichloroacetimidate activation. The anomeric substituent at the reducing end of the disaccharide acceptor has a remarkably strong influence on glycosidic coupling; a thiophenyl-substituted disaccharide was observed to be an unusually poor glycosyl acceptor in comparison with the corresponding allyloxy-substituted disaccharide.
