A copper-catalyzed three-component annulation for the synthesis of functionalized 2-quinolones was developed. Three reactions including an SN2, a Knoevenagel, and finally C–N bond formation are involved in the designed cascade reaction using 2-bromoacylarenes, 2-iodoacetamide, and nucleophiles as the three components. A new catalytic system was discovered during the study and this modular approach
开发了一种用于合成功能化 2-喹诺酮类的铜催化三组分环化。使用 2-溴代芳烃、2-碘乙酰胺和亲核试剂作为三个组分的设计级联反应涉及三个反应,包括 S N 2、Knoevenagel 和最后形成 C-N 键。研究期间发现了一种新的催化系统,这种模块化方法可以高效地获得功能化的 2-喹诺酮衍生物,与广泛的官能团兼容,可扩展且经济。所得产物的进一步衍生证明了该方法的合成效用。
