1,2-<i>Trans</i>-Selective Synthesis of Glycosyl Boranophosphates and Their Utility as Building Blocks for the Synthesis of Phosphodiester-Linked Disaccharides
is controlled by neighboring group participation. The resultant glycosyl boranophosphate triesters were converted into the corresponding boranophosphate diesters and condensed with appropriately protected monosaccharides to give disaccharides linked with an anomeric boranophosphate linkage. Furthermore, the disaccharides worked as precursors of the corresponding phosphodiester-linked disaccharides

A one-pot synthesis of glycosyl phosphates and their P-modified analogs from glycosyl boranophosphates under mild basic conditions has been conducted. 31P NMR monitoring of the reaction mixture revealed that the key intermediates of these reactions were acyl phosphites, which could not be formed from the corresponding H-phosphonate diesters.
已经在温和的碱性条件下从糖基硼酸磷酸酯一锅法合成糖基磷酸酯及其P-修饰的类似物。反应混合物的31 P NMR监测表明,这些反应的关键中间体是酰基亚磷酸酯,无法由相应的H-膦酸酯二酯形成。
