Synthesis of ethyl 5-O-(alpha-D-arabinofuranosyl)-6-O-(beta-D-galactofuranosyl)-beta-D- galactofuranoside present in motif E of the Mycobacterium tuberculosis cell wall.

[figure: see text] The stereocontrolled synthesis of the trisaccharide ethyl 5-O-(alpha-D-arabinofuranosyl)-6-O-(beta-D-galactofuranosyl)- beta-D-galactofuranoside present in motif E of the Mycobacterium tuberculosis cell wall is described.

Synthesis of oligosaccharides of motifs D and E of arabinogalactan present in mycobacterium tuberculosis

Syntheses of the ethyl glycosides of 5-O-(β-D-galactofuranosyl)-β-D-galactofuranose and 5-O-(α-D-arabinofuranosyl)-6-O-(β-D-galactofuranosyl) -β-D-galactofuranose present in motifs D and E of Mycobacterium tuberculosis arabinogalactan, respectively, have been presented. The pentenylmediated O-glycosylation reaction was utilized to obtain the disaccharide of motif D. The first coupling reaction to prepare the inner disaccharide portion of motif E was accomplished by trichloroacetamidate method while the installation of the terminal sugar by pentenyl glycosylation approach was successful.
