[Synthesis of oligosaccharide fragments of O-specific polysaccharides of Shigella flexneri. III. Synthesis of the tetrasaccharide Glc alpha 1-3Rha alpha 1-2(Glc alpha 1-3)Rha alpha 1-OMe and the pentasaccharide GlcNAc beta 1-2(Glc alpha 1-3)Rha alpha 1-2(Glc alpha 1-3)Rha alpha 1-OMe].
Two synthetic schemes to prepare the title branched tetrasaccharide and pentasaccharide are described. These oligosaccharides represent fragments of the O-antigenic polysaccharides of Shigella flexneri serotype 5b.
