The synthesis of chloroethylnitrososulfamide, (CENS), was carried out starting from chlorosulfonyl isocyanate, amines and haloalcohols through heterocyclization and decarboxylative reopening of N-sulfamoyl-2-oxazolidinones. A total regioselectivity concerning CO2 versus SO2 site hydrolysis was observed. A related aminolysis of sulfamoyloxazolidinones gave N-carbamoylsulfamides. The specific nitrosation
氯乙基亚硝基磺酰胺(CENS)的合成是从氯磺酰基异氰酸酯,胺和卤代醇开始,通过N-氨磺酰基-2-恶唑烷酮的杂环化和脱羧重开来进行的。观察到关于CO 2相对于SO 2位点水解的总区域选择性。氨磺酰基恶唑烷酮的相关氨解产生了N-氨基甲酰基磺酰胺。N-氯烷基部分上的特定亚硝化可以在氨磺酰基恶唑烷酮甲基化之后获得。
