A direct and catalytic method is reported here for β‐arylation of N‐protected lactams with simple aryl iodides. The transformation is enabled by merging soft enolization of lactams, palladium‐catalyzed desaturation, Ar−X bond activation, and aryl conjugate addition. The reaction is operated under mild reaction conditions, is scalable, and is chemoselective. Application of this method to concise syntheses
此处报道了一种直接催化方法,用于将N保护的内酰胺与简单的芳基碘化物进行β-芳基化反应。通过合并内酰胺的软烯醇化,钯催化的去饱和,Ar-X键活化和芳基共轭物加成,可以实现该转化。该反应在温和的反应条件下进行,具有可扩展性,并且具有化学选择性。证明了该方法在简明药物相关化合物的合成中的应用。
