开发了一种方便实用的无金属可见光促进室温合成3-烷氧基化喹喔啉-2(1H)-酮的方法。目前的转化可以通过Rose Bengal催化的喹喔啉-2(H)-酮与简单醚的C-H/C-H交叉脱氢偶联来完成，提供了一种有效且操作简单的方法来获得各种3-氧基烷基化喹喔啉-2(1H)-酮，并具有中等至良好的产率。
A convenient and practical metal-free visible-light-promoted method to synthesize 3-oxyalkylated quinoxalin-2(1H)-ones was developed at room temperature. The present transformation could be accomplished through Rose Bengal-catalyzed C–H/C–H cross-dehydrogenative-coupling of quinoxalin-2(H)-ones with simple ethers, providing an efficient and operationally simple method to access various 3-oxyalkylated quinoxalin-2(1H)-ones with moderate to good yields.
