Abstract:
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-9-enyl β-D-Galf-(1→6)-β-D-Galf-(1→ 5)-β-D-Galf (2) and dec-9-enyl β-D-Galf-(1→5)-β -D-Galf-(1→6)-β-D Galf (9) so far reported as convenient substrates for the galactofuranosyl transferase, and possibly useful for immunological studies, were obtained by the trichloroacetimidate method of glycosylation.
