a [3+5] convergent synthesis of an outer core octasaccharide of H. pylori employing just three orthogonally protected building blocks. A synergistic glycosylationstrategy enables the creation of five pivotal 1,2‐cis‐α‐glucosidic bonds consist of four types of linkages using just three monomers. This strategy can be expanded to many 1,2‐cis‐α‐gluoside‐containing oligosaccharides both in solution and

spacer-equipped protected derivative of the common 3,4-branched diheptoside trisaccharide structure of the lipopolysaccharide core of Neisseria meningitidis and Haemophilus influenzae has been synthesized. The protecting group pattern installed allows regioselective introduction of phosphoethanolamine residues in the 3- and 6-position of the second heptose unit in accordance with native structures. From this intermediate
