that despite the presence of three active amino moieties of carbamoylguanidine, it adds to sulfonyl chloride by the amino group, not the carbamoyl groups, to give monosulfonamides. Being 1,3-dipolar compounds, the arylsulfonylcarbamoylguanidines obtained readily add to polarophiles, such as chloroacetonitrile and benzoin, to form imidazolylsulfonamides or make pyrimidinylsulfonamides by reacting with arylidene
已经发现,尽管存在氨基甲酰基胍的三个活性氨基部分,但它通过氨基而不是氨基甲酰基基团向磺酰氯添加,得到单磺酰胺。作为1,3-偶极化合物,获得的芳基磺酰基氨基甲酰基胍易于与亲脂性物质如氯乙腈和安息香相加,形成咪唑基磺酰胺或通过与亚芳基丙二醛反应生成嘧啶基磺酰胺。对磺酰基-2-氨基甲酰基胍在N-烷基化反应中的反应性的研究表明,该反应通过在磺酰胺氮上置换氢原子而异常地进行。检查一些磺酰基-N-氨基甲酰基胍衍生物在润滑油和脂中显示出高的防锈和摩擦学性能,以及抗微生物活性。
