Abstract
Hydrogenphosphonate method was used for synthesis of 4-nitrophenyl 2-acetamido-3- and 4-nitrophenyl 2-acetamido-4-(2-acetamido-2-deoxy-alpha-D-glucopyranosyl phosphate)-2-deoxy-beta-D-glucopyranosides. The glycosides, phosphate diester fragments of the title bacteria capsular antigens, were obtained by H-phosphorylation of the suitably protected 2-acetamido-2-deoxy-beta-D-glucopyranosides with 2-acetamido-3,4,6-tri-O-benzoyl-2-deoxy-alpha-D-glucopyranosyl H-phosphonate in the presence of trimethylacetyl chloride followed by oxidation and deprotection.
