[Synthesis of (2-acrylamidoethyl)-3-O- (3,6-dideoxy-alpha-D-xylo-hexopyranosyl)-alpha and beta-rhamnopyranosides for preparation of polyacrylamide copolymers with the specificity of O:8 factor of Salmonella].

Condensation of (2-trifluoracetamidoethyl) 2-O-acetyl-4-O-benzoyl-alpha-L-rhamnopyranoside and (2-trifluoroacetamidoethyl) 2,4-di-O-benzyl-beta-L-rhamnopyranoside with 3,6-dideoxy-2,4-di-O-(p-nitrobenzoyl)-alpha-D-xylo-hexopyranosyl bromide followed by deprotection and N-acryloylation gave (2-acrylamidoethyl) 3-O-(alpha-abequopyranosyl)-alpha-and-beta-L-rhamnopyranosides+ ++, respectively. The glycosides obtained were converted, via radical copolymerization with acrylamide, into copolymers having as branches disaccharide determinants of the 0 : 8 factor of Salmonella.
