A protocol for palladium-catalyzed C–H carbonylation of readily available free primary benzylamines using NH2 as the chelating group under an atmospheric pressure of CO has been achieved, providing a general, atom- and step-economic approach to benzolactams, an important structural motif found in many biologically active compounds. Application of this new method is also exemplified in the concise syntheses
在大气压力下,使用NH 2作为螯合基团,已经实现了钯催化的易得的游离伯苄胺的CH-H羰基化反应的协议,为苯并内酰胺(一种重要的结构)提供了通用的,原子经济的和分步经济的方法。在许多具有生物活性的化合物中发现的基序。在两个生物活性分子的简明合成中也举例说明了这种新方法的应用。
