Synthesis of the 6-O-methyl-D-glycero-α-L-gluco-heptopyranose moiety present in the capsular polysaccharide from Campylobacter jejuni NCTC 11168.

The first synthesis of the 6-O-methyl-D-glycero-α-L-gluco-heptopyranose moiety present in the capsular polysaccharide from Campylobacter jejuni NCTC 11168 is reported. The target (1) was synthesized as the 8-aminooctyl glycoside and then conjugated to bovine serum albumin (BSA) for the generation of antibodies recognizing this motif. Heptose 1 was obtained from D-galactose via a series of galactofuranose derivatives.
