Synthesis of glycans from the glycodelins: Two undeca-, two deca-, three nona-, an octa- and a heptasaccharide

The concise synthesis of nine diantennary oligosaccharides by chemical and chemoenzymatic protocols is presented. The compounds display Lewis X, Lewis Y, sialyl Lewis X and T-antigen epitopes supported on a 3,6-branched trimannose core. A chemical approach was adopted for the synthesis of the unsymmetrically decorated structures and those that could not be accessed by enzymatic decoration of a core heptasaccharide.
