Abstract
The synthesis of chloroethylnitrososulfamides (CENS), was carried out starting from chlorosulfonyl isocyanate, amines and haloalcohols throu gh heterocyclization and decarboxylative reopening of N-sulfamoyl-2-ox azolidinones. A total regioselectivity concerning CO2 versus SO2 site hydrolysis was observed. A related aminolysis of sulfamoyloxazolidinon es gave N-carbamoylsulfamides. The specific nitrosation on the N-chlor oalkyl moiety can be obtained after methylation of the sulfamoyloxazol idinones. Copyright (C) 1996 Elsevier Science Ltd
