the reaction are probed. It was found that the N-sulfonyl- N′-substituted thioureas cannot possess internal nucleophiles or disubstitution, and that the incoming amine must possess adequate nucleophilicity in order for the reaction to be viable. However, it is noted that the guanidine products can be accessed through two possible synthetic approaches, and that a simple reversal of amine and thiourea
概述了 EDCI 介导的胺与 N-Pmc-N'-烷基硫脲生成胍的简便且高产率的反应,其中探讨了该反应的一般范围和局限性。发现 N-磺酰基-N'-取代的硫脲不能具有内部亲核试剂或双取代,并且进入的胺必须具有足够的亲核性才能使反应可行。然而,值得注意的是,胍产物可以通过两种可能的合成方法获得,并且胺和硫脲取代基的简单反转可以使反应成功进行。
