标题:Synthesis of glycosides having predetermined stereochemistry
发明人：DANISHEFSKY SAMUEL J
权利人:UNIV YALE
摘要:Methods of stereoselectively preparing a substituted 1,2-anhydrosugar wherein a substituted glycal is converted into a 1,2-anhydrosugar that is utilized to glycosylate a hydroxyl group containing glycal, are disclosed. Methods of preparing a saccharide multimer wherein a nucleophile is reacted with a substituted 1,2-anhydrosugar having a plurality of non-participating substituents, are disclosed. In addition, methods of preparing stereospecific halo-substituted saccharide multimers by haloglycosylation of a glycosyl donor substituted glycal and a glycosyl acceptor glycal derivative in the absence of water and in the presence of a halonium ion, are disclosed. Methods of preparing stereospecific particle-linked halo-substituted saccharide multimers, by haloglycosylation of a particle-linked nucleophilic hydroxyl group with a substituted glycal and a halonium ion, are also disclosed.
