An efficient method for the synthesis of quinoxaline N‐oxides proceeds by the dehydrogenative N‐incorporation of simple imines by C(sp2)H and C(sp3)H bond functionalization. The overall transformation involves the cleavage of three CH bonds. The reaction is easily handled and proceeds under mild conditions. Simple and readily available tert‐butyl nitrite (TBN) was employed as the NO source.
一种有效的合成喹喔啉N-氧化物的方法是通过C(sp 2)H和C(sp 3)H键功能化使简单的亚胺脱氢N-并入。整体转化涉及三个CH键的裂解。该反应易于处理并在温和条件下进行。简单易得的亚硝酸叔丁酯(TBN)被用作NO源。
