  Acceptor-Dependent Stereoselective Glycosylation:  2‘-CB Glycoside-Mediated Direct β-d-Arabinofuranosylation and Efficient Synthesis of the Octaarabinofuranoside in Mycobacterial Cell Wall

  摘要：

  A reliable and generally applicable direct method for the stereoselective beta-arabinofuranosylation employing a 2'-carboxybenzyl arabinofuranoside as the glycosyl donor has been established. The acyl-protective group on glycosyl acceptors is essential for the beta-stereoselectivity. The power of the present acceptor-dependent glycosylation method was demonstrated by the efficient synthesis of the octaarabinofuranoside in arabinogalactan and lipoarabinomannan found in mycobacterial cell wall.

  The synthesis of 11 oligosaccharides (4-14) containing beta-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 beta-arabinofuranosyl residues with good

  1-O-Acetylfuranoses and pyranose 1,2-orthoesters were activated with an AuIII halide/phenylacetylene relay catalyst system, and they acted as excellent glycosyl donors. Thus, 1-O-acetyl-D-ribofuranose, 1-O-acetyl-D-lyxofuranose, and 1,2-orthoesters selectively gave the corresponding 1,2-trans glycosides, whereas 1-O-acetyl-D-arabinofuranose and 1-O-acetyl-D-xylofuranose both gave mixtures of 1,2-trans
