Abstract

An efficient palladium-catalyzed cascade reaction of azides with isonitrile and amines is presented; it offers an alternative facile approach toward N-sulfonyl-, N-phosphoryl-, and N-acyl-functionalized guanidines in excellent yield. These series of substituted guanidines exhibit potential biological and pharmacological activities. In addition, the less reactive intermediate benzoyl carbodiimide could be isolated by silica gel column flash chromatography in moderate yield.

钯催化一锅法合成N-磺酰基，N-磷酰基和N-酰基胍

摘要

提出了一种有效的钯催化的叠氮化物与异腈和胺的级联反应。它为N-磺酰基-，N-磷酰基-和N-酰基官能化的胍提供了另一种简便的方法，收率很高。这些取代的胍系列显示出潜在的生物学和药理活性。另外，可以通过硅胶柱快速色谱法以中等收率分离反应性较低的中间体苯甲酰基碳二亚胺。
