A self-photocatalyzed sulfonylation/cyclization method for quinazolinones with unactivated alkenes and various sulfonyl chlorides has been developed, allowing access to sulfonyl radicals without the need for external photocatalysts or oxidants. This provides an alternative route for synthesizing sulfonylated compounds.
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.
