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.

标 题 :Method for producing intermediate useful for synthesis of SGLT inhibitor
发明人：LI QING RI; YOON HEE KYOON
权利人:DAEWOONG PHARMACEUTICAL CO LTD
摘要:A method of preparing an intermediate useful for the synthesis of a diphenylmethane derivative that can be used as an SGLT inhibitor is described. A method of synthesizing a compound of Formula 7 can address problems of existing synthesis processes requiring the synthesis of the Grignard reagent and management of related substances. In addition, the method can minimize the generation of related substances, and thus does not require reprocessing of reaction products, thereby simplifying the process. Accordingly, the production yield of a diphenylmethane derivative can be maximized.
