• Facile preparation of glycosyl donors for oligosaccharide synthesis: 2-azido-2-deoxyhexopyranosyl building blocks

  日期：1994.11

  Facile routes to the 2-azido-2-deoxy-1-thioglycosides 6, 7, 15, and 18 and of the 2-azido-2-deoxy-4-pentenoglycoside 11, are described. These are useful intermediates for the synthesis of oligo-saccharides containing alpha-D-2-amino-2-deoxy (or 2-acetamido-2-deoxy) hexosyl residues in the galacto-, gluco-, and manno- series.
• Synthesis of <i>Staphylococcus aureus</i> Type 5 Trisaccharide Repeating Unit: Solving the Problem of Lactamization

  The chemical synthesis of an orthogonally protected trisaccharide derived from the polysaccharide of Staphylococcus aureus Type 5, which is an attractive candidate for the development of immunotherapies, is described. The challenging alpha-fucosylation and beta-mannosylation are addressed through the careful choice of protecting groups. Lactamization of a beta-D-ManpNAcA moiety during deprotection was avoided by a late stage oxidation approach. Versatility of the trisaccharide was demonstrated by its transformation into a spacer-containing repeating unit suitable for immunological investigations.
