Arabinofuranosides from mycobacteria: Synthesis of a highly branched hexasaccharide and related fragments containing β-arabinofuranosyl residues

The synthesis of 11 oligosaccharides (4-14) containing β-arabinofuranosyl residues is reported. The glycans are all fragments of two polysaccharides, arabinogalactan and lipoarabinomannan, which are found in the cell wall complex of mycobacteria. In the preparation of the targets, the key step was a low-]temperature glycosylation reaction that installed the β-arabinofuranosyl residues with good to excellent stereocontrol.

The first total synthesis of a highly branched arabinofuranosyl hexasaccharide found at the nonreducing termini of mycobacterial arabinogalactan and lipoarabinomannan
