Synthesis of N-aryl spiro-sulfamides as potential glycogen phosphorylase inhibitors

Abstract

A new C-glucosylated spiro-sulfamide has been prepared and evaluated toward glycogen phosphorylase inhibition. The synthesis was carried out successfully by nucleophilic displacement of 1- O-tosyl or 1-deoxy-1-iodo-α- d- gluco-hept-2-ulopyranose tetra- O-benzylated derivative using aryl amines, followed by the formation of the corresponding cyclic sulfamide.
