title: Synthesis of oligosaccharide fragments of the repeating unit of Salmonella kentucky O-specific polysaccharide and conversion of the oligosaccharides into the glycosyl phosphates.
abstract: alpha-D-Man-(1----2)-alpha-D-Man-(1----3)-D-Gal, a structural fragment of the main chain of Salmonella serogroups C2 and C3 O-specific polysaccharides, and the isomer with the central residue beta have been synthesised, as have some oligosaccharides related to the structure of the O-specific polysaccharide of S. kentucky (serogroup C3), namely, alpha-D-Glc-(1----4)-D-Gal, alpha-D-Man-(1----3)-[alpha-D-Glc-(1----4)]-D-Gal, and alpha-D-Man-(1----2)-alpha-D-Man-(1----3)-[alpha-D-Glc-(1----4)]-D-Gal, and the isomers with the D-Glc unit beta. Each oligosaccharide was converted into the alpha-glycosyl phosphate.
