摘要：We report a visible light-promoted cyclization/sulfonylation cascade of N-heterocycles with thianthrenium salts using DABSO as the SO₂ surrogate. This method features excellent functional group tolerance, wide substrate scope and late-stage elaboration of bioactive relevant molecules. Mechanistic investigations reveal that the photoactive electron donor−acceptor (EDA) complexes between thianthrenium salts and DABCO are capable of the generation of aryl radicals which induces the following SO₂ insertion by attacking DABSO, thus triggering the key radical cyclization step.
