Synthesis of O-glycopyranosyl-N-hydroxysuccinimides of glucose and lactose and their opening by nucleophiles into prespacer glycosides.

abstract：:A major impediment in the analysis of glycosaminoglycans is the difficulty to cleave quantitatively the glycosidic bonds because of the stabilisation of glycosidic bonds and of the relative instability of the liberated constituents. This manuscript describes a modified procedure of methanolysis in the presence of bari...
