Photo‐Triggered Self‐Induced Homolytic Dechlorinative Sulfonylation/Cyclization of Unactivated Alkenes: Synthesis of Quinazolinones Containing a Sulfonyl Group

Photo‐Triggered Self‐Induced Homolytic Dechlorinative Sulfonylation/Cyclization of Unactivated Alkenes: Synthesis of Quinazolinones Containing a Sulfonyl Group

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...

Zusammenfassung: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.
