The synthesis of a-1-C-propyl-3,6-di-epi-nojirimycin and Polyhydroxyindolizidine alkaloids from readily available a-methyl-D-mannopyranoside is described. The key step in this process involves a regioselective and diastereoselective amination of the anomeric acetal functionality using chlorosulfonyl isocyanate (CSI).
