A facile palladium-catalyzed synthesis of acridines has been realized by consecutive C=C double bond formation and C–N cross-coupling. A variety of functionalized acridines can be accessed from easily available o-dihalobenzenes and N-tosylhydrazones in a single operation. This one-pot protocol has a wide scope with respect to both coupling partners, and provides an efficient route to functionalized
通过连续的C=C双键形成和C-N交叉偶联实现了钯催化合成吖啶的简便方法。各种功能化的吖啶可以通过简单的操作从容易获得的邻二卤代苯和 N-甲苯磺酰腙中获得。这种一锅法在两个耦合伙伴方面具有广泛的范围,并为功能化吖啶衍生物提供了一种有效的途径,这些衍生物通常难以通过以前已知的方法合成。
