1,2,5-ortho esters of D-arabinose were found to be
ideally suited building blocks for the stereoselective formation of α
and β arabinofuranosidic linkages after nucleophilic opening of the
orthoester with oxygen and sulfur nucleophiles; the tetrasaccharidic cap of
the lipoarabinomannan of Mycobacterium tuberculosis was then
synthesized in a highly convergent manner.

1,2,5-Orthoesters of D-arabinose are key compounds for the construction of a glycosylation system that allows the stereoselective synthesis of any interglycosidic linkage between arabinofuranosidic units. Application to the synthesis of a pentaarabinofuranoside of the mycobacterial cell wall is also described. (C) 2000 Elsevier Science Ltd. All rights reserved.
