Synthesis of the pentasaccharide repeating unit of Escherichia coli O128 antigen

A pentasaccharide, 4-methoxyphenyl 2-acetamido-2-deoxy-β-d- galactopyranosyl-(1→4)-α-d-galactopyranosyl-(1→3) -2-acetamido-2-deoxy-β-d-galactopyranosyl-(1→6)-[α-l- fucopyranosyl-(1→2)]-β-d-galactopyranoside (1), representing the repeating unit of Escherichia coli O128 antigen, was successfully prepared in 23% overall yield via a convergent '2+3' glycosylation strategy.
