A simple and efficient visible‐light‐promoted selenylation/cyclization of enaminones have been realized for the practical synthesis of 3‐selanyl‐4H‐chromen‐4‐ones. This reaction is performed in the mild conditions, no transition metal catalyst or photocatalysts and no additional oxidants are required. In addition, the 3‐selanyl‐4H‐chromen‐4‐ones could be easily converted to selanyl‐functionalized pyrimidines by reacting with benzamidine substrates.

可见光促进烯胺酮的烯丙基化/环化，形成3-Selanyl-4H-Chromen-4-Ones。

已经实现了简单而有效的可见光促进的烯胺酮的硒化/环化反应，可实际合成3-Selanyl-4 H -chromen-4- 。该反应在温和的条件下进行，不需要过渡金属催化剂或光催化剂，也不需要其他的氧化剂。此外，通过与苯甲idine底物反应，可以很容易地将3-selanyl-4 H -chromen-4 -ones转化为selanyl-functionalized嘧啶。
