  Exploring the Native Chemical Ligation Concept for Highly Stereospecific Glycosylation Reactions

  摘要：

  Various O-alkyl glycosides were obtained in a highly stereospecific manner with retention of configuration at the anomeric center. Our method has customized native chemical ligation concept for glycoconjugates synthesis, utilizing a meticulously controlled activating system. To explain the origin of stereoselective preference, an S(N)i mechanism was proposed and corroborated by computational calculations.
