  Synthesis of a hexasaccharide fragment of group E streptococci polysaccharide and the tetrasaccharide repeating unit of E. coli O7:K98:H6

  摘要：

  Syntheses of a hexasaccharide, the dimer of the repeating unit of the group E streptococci polysaccharide, and a tetrasaccharide, the repeating unit of the E. coli 07:K98:H6, were achieved by constructing alternate alpha-L-(l --> 2)- and alpha-L-(1 --> 3)linked L-rhamnopyranose backbones and substituting with beta-linked D-glucopyranose side chains for the former, and a D-gluco-pyranosyluronate branch for the latter, respectively, at O-2 of the L-rhamnose ring.
