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
