Chemical synthesis of the 4-amino-4,6-dideoxy-d-glucose containing pentasaccharide repeating unit of the O-specific polysaccharide from Aeromonas hydrophila strain K691 in the form of its 2-aminoethyl glycoside. | LitMetric

AI Article Synopsis

  • * The synthesis method involved sequentially building the pentasaccharide from a common disaccharide and adding a rare sugar unit at the end.
  • * The final product was created as a 2-aminoethyl glycoside, which is important for creating glyconjugates, using stereoselective glycosylations activated by specific reagents.

Article Abstract

Chemical synthesis of the pentasaccharide repeating unit of the O-specific polysaccharide from Aeromonas hydrophilastrain K691 is reported. Synthesis of the pentasaccharide is accomplished by using a common disaccharide in sequence and finally attaching the rare sugar unit. The target structure was made in the form of its 2-aminoethyl glycoside which is essential for further glycconjugate formation. Stereoselective glycosylations were achieved by the activation of thioglycosides in the presence of HSO-silica in conjunction with N-iodosuccinimide.
