A self-photocatalyzed sulfonylation/cyclization of quinazolinones containing unactivated alkenes with various sulfonyl chlorides was developed. The protocol provides access to sulfonyl radicals via energy transfer from the quinazolinone skeleton to the sulfonyl chloride. Notably, the transformations proceeded without any external photocatalysts, additives, or oxidants, providing an alternative method for fabricating sulfonylated compounds.

未活化烯烃的光触发自诱导均裂脱氯磺酰化/环化：含有磺酰基的喹唑啉酮的合成

开发了含有未活化烯烃的喹唑啉酮与各种磺酰氯的自光催化磺酰化/环化。该协议通过从喹唑啉酮骨架到磺酰氯的能量转移提供了对磺酰基自由基的访问。值得注意的是，这些转化在没有任何外部光催化剂、添加剂或氧化剂的情况下进行，为制造磺酰化化合物提供了一种替代方法。
