[Synthesis of oligosaccharide fragments of O-specific Shigella flexneri polysaccharides. II. Synthesis of trisaccharide Glc alpha1----3RHa alpha1----2Rha alpha1----OMe and tetrasaccharide GlcNAc beta1----2(Llc alpha1----3)Rha alpha1----2Rh alpha1----OMe].
Methyl glycosides of the title linear trisaccharide and branched tetrasaccharide were synthesized by stepwise glycosylation. These oligosaccharides represent the fragments of O-antigenic polysaccharides of Shigella flexneri serotypes 2b, 3a, 5b, and X.
