AI Article Synopsis
- Researchers created a variety of fused tricyclic heterocycles using a process involving the dimerization and cyclization of benzene derivatives when exposed to visible light.
- The process is initiated by aryloxy radicals formed through a reaction involving proton-coupled electron transfer from a photoexcited vinylidene-quinone methide (VQM) and a Brønsted base.
- This method highlights the innovative use of light and unique chemical reactions to synthesize complex compounds.
Article Abstract
A diverse array of fused [6-6-5] tricyclic heterocycles has been synthesized the dimerization and dearomative cyclization of benzene derivatives under visible light irradiation. The initiation of the cascade process is likely from aryloxy radicals, engendered through proton-coupled electron transfer by the photoexcited vinylidene -quinone methide (VQM) and a Brønsted base.
