A general and efficient synthesis of diverse tetracyclic indolo[2,3-b]quinoline derivatives was achieved through palladium-catalyzed domino carboannulation/cross-coupling and DDQ-mediated double cross-dehydrogenative C–N bond formation. This approach provides a straightforward, atom-economical and concise route to easily access a diverse range of tetracyclic indolo[2,3-b]quinolines and their analogues
通过钯催化的多米诺碳环化/交叉偶联和DDQ介导的双交叉脱氢C-N键的形成,可以实现多种四环吲哚并[2,3- b ]喹啉衍生物的一般有效合成。该方法提供了一种简单,原子经济且简洁的途径,可以轻松获得具有优良收率且对官能团具有良好耐受性的各种四环吲哚并[2,3- b ]喹啉及其类似物。
