important antigenic determinants. A novel entry to anthrose-containing antigens and precursors is described. The synthetic route, starting from d(+)-fucose, makes use of intermediates featuring a cyclicsulfite or sulfate function which serves successively as a protecting and a leaving group.

Anthraxtetrasaccharide is an oligosaccharide expressed at the outermost surface of the Bacillus anthracis spores, featuring three rhamnoses and a rare sugar called anthrose. This motif has now been identified as a plausible component of future human vaccines against anthrax. We report herein the synthesis of a 2-O-demethylated-β-D-anthropyranosyl-(1→3)-α-L-rhamnopyranose disaccharide analogue of this
