摘要:Disclosed is synthesis of an O-Antigen oligosaccharide compound of Helicobacter pylori serotype O2, belonging to the field of organic synthesis. The disclosure obtains O-antigen disaccharide to tetracosasaccharide of Helicobacter pylori serotype O 2 by chemical synthesis. A chemical synthesis method which is quite conducive to production of a glucose-α-lglucosidic bond is developed in the disclosure by a protectant strategy, temperature effect, solvent effect, and additive effect. The method is applied in synthesis of an O-antigen oligosaccharide compound of Helicobacter pylori serotype O2 assembled with an amino linking arm. A saccharide conjugate can be prepared from the synthesized O-antigen oligosaccharide compound of Helicobacter pylori serotype O2 assembled with an amino linking arm together with a carrier protein for immunology researches, playing an important role in preventing and treating Helicobacter pylori.
