Syntheses of β-D-Galf-(1→6)-β-D-Galf-(1→5)-D-Galf and β-D-Galf-(1→5)-β-D-Galf-(1→6)-D-Galf, trisaccharide units in the galactan of Mycobacterium tuberculosis

The galactofuran is a crucial constituent of the cell wall of mycobacteria. An efficient synthesis of the two trisaccharide units of the galactan is described. The strategy relies on the use of substituted D-galactono-1,4-lactones as precursors for the internal and the reducing galactofuranoses. Dec...
