Syntheses of hexadecasaccharide and smaller fragments corresponding to one-four repeating units of the O-specific polysaccharide of Shigella dysenteriae type 1 are reported in a reactive aglycon-linked from. Two tetrasaccharide donor/acceptor repeating units were assembled from monosaccharide precursors in a stepwise fashion and used in a linear, iterative manner to construct the higher-membered saccharides using Schmidt's glycosylation technique that proved superior to others tested. Single-point attachment of the saccharides to human serum albumin, using a secondary heterobifunctional spacer, afforded a range of glycoconjugates for a detailed evaluation of their immunological characteristics.
