straightforward synthesis of halogen‐containing quinolin‐2(1H)‐ones. The reaction proceeds without preactivation and directing groups through direct N–H and C–H bond activation with a broad substrate scope and high efficiency. Halogen functional groups can be well tolerated here. Remarkably, this is the first example of an iridium‐catalyzed carbonylative C–H activation of anilines.
喹啉2(1 H)-1是重要的化学药品,在制药中有多种应用。在本文中,我们开发了一种新颖且有效的铱催化的带有内部炔烃的简单苯胺的羰基环化反应,可直接合成含卤素的喹啉-2(1 H)-酮。反应在没有预活化的情况下进行,并通过直接的N–H和C–H键活化来引导基团,具有广泛的底物范围和高效率。此处可以很好地耐受卤素官能团。值得注意的是,这是铱催化苯胺的羰基CH活化的第一个例子。
