A direct C–H alkylation of quinoxalinones at the C‐3 position with sodium alkylsulfinates and phenyliodine(III) dicarboxylates has been developed under catalyst‐free conditions. A series of 3‐alkylquinoxalinones were afforded in moderate to excellent yields in this protocol, which offers a practical and efficient access to biologically interesting 3‐alkylquinoxalin‐2(1H)‐one derivatives.
在无催化剂的条件下,已开发了在烷基的C-3位置与烷基亚磺酸钠和苯基碘(III)二羧酸直接对喹喔啉酮进行CH烷基化反应。在该方案中,以中等到极好的产率提供了一系列3-烷基喹喔啉酮,这为生物学上令人感兴趣的3-烷基喹喔啉-2(1 H)-one衍生物提供了实用而有效的途径。
