A highly concise and effective synthesis of α(1 → 2)-linked manno- and rhamnopyranosyl oligosaccharides was achieved via TMSOTf promoted condensation of the corresponding benzoylated monosaccharide alkyl orthoester. α(1 → 2)-Linked mannosyl tetra- and octasaccharide, rhamnosyl tetrasaccharide, antigenic factor 4, and dominant of antigenic factor 6 were readily synthesized by the new method.
