A metal-free, TBHP-promoted economical route is developed via the sp2 C–H bond functionalization strategy for the synthesis of indenoquinolinones, 4-azafluorenones and fluorenones. Reactions provided excellent yield of the products under mild conditions. We have successfully synthesized 11H-indeno[1,2-b]quinolin-11-one, an antibacterial agent, in excellent yields.
通过sp 2 C–H键官能化策略开发了无金属,TBHP促进的经济路线,用于合成茚并喹啉酮,4-氮杂芴酮和芴酮。反应在温和的条件下提供了优异的产物收率。我们已经成功地以优异的产率成功合成了11 H-茚并[1,2- b ]喹啉-11-one。
