A novel, efficient and practical method for copper-catalysed oxidative C-3 amination of quinoxalin-2(1H)-ones with primary or secondary amines as the nitrogen sources has been developed. A wide variety of 3-aminoquinoxalin-2(1H)-ones were prepared in up to 98% yield with good functional group tolerance for 24 examples. This synthetic strategy features atom economy, concise steps, easy operation, and
已开发出一种新颖,有效,实用的方法,以伯胺或仲胺为氮源,对喹喔啉-2(1 H)-进行铜催化的C-3氧化胺化反应。对于24个实例,制备了多种3-氨基喹喔啉-2(1 H)-1,产率高达98%,具有良好的官能团耐受性。这种合成策略具有原子经济,步骤简明,操作简便和反应条件温和的特点。
