An oxidation–amidation approach for the synthesis of glycuronamides
A route for the synthesis of glycuronamides via the variety of carbohydrate residues and protecting groups, was intermediacy of 6-S-tolyl-substituted glycosides and uronic acid used to synthesize the repeating unit of the E. coli K54 capsular thioesters, is reported. The route, which is compatible with a polysaccharide.
