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.

With eco-friendly and sustainable CO2-derived dimethyl carbonate as the sole solvent, the visible-light-induced cascade radical reactions have been established as a green and efficient tool for constructing various CHF2/CClF2/CBrF2-substituted ring-fused quinazolinones.

A novel and green strategy for the synthesis of acylated quinazolinone derivativesviaphoto-induced decarboxylative cascade radical acylation/cyclization of quinazolinone bearing unactivated alkenes has been developed. The protocol provides a novel route to access acyl radicals from α-keto acids through a self-catalyzed energy transfer process. Most importantly, the reaction proceeded smoothly without any external photocatalyst, additive or oxidant, and could be easily scaled-up in flow conditions with sunlight irradiation.
