phosphorus oxychloride, or phosphorus pentachloride. We report here a safer and more convenient synthetic methodology for large-scale preparation of sulfamides using the N-substituted oxazolidin-2-one derivatives 5 as synthetic equivalent of the corrosive and hazardous N-sulfamoyl chloride. The scope of the use of N-sulfamoyloxazolidinones to prepare nonsymmetrical sulfamides is explored.
