metal-free promoted direct oxidative C–N bond coupling of quinoxalinones and azoles for the rapid and effective synthesis of potent pharmaceutical important 3-(azol-1-yl)quinoxalin-2-one has been developed. Employing PIDA as the easily available mediator, the desired coupling products were isolated in moderate to excellent yields with a good substrate scope under operational simplicity and mild reaction conditions
已开发出无金属促进的喹喔啉酮和唑类的直接氧化C–N键偶联,可快速有效地合成有效的重要药物3-(azol-1-yl)quinoxalin-2-one。利用PIDA作为易于获得的介体,在操作简便和温和的反应条件下,以中等至极好的收率分离了所需的偶联产物,并具有良好的底物范围。初步的机理研究表明,该反应可能涉及自由基过程。
