Described is a convenient method for the syntheses of sulfur and selenium containing carbohydrate derivatives of L-gulodeoxynojirimycin and the corresponding C-5 epimer D-mannodeoxynojirimycin. The key step in the synthesis of the latter involves epimerisation of the C-5 hydroxyl group by an oxidation followed by stereo-selective reduction to obtain the desired D-sugar derivative. Both derivatives
