Brønsted Acid Catalysis in Visible‐Light‐Induced [2+2] Photocycloaddition Reactions of Enone Dithianes
1,3‐Dithiane‐protected enones (enone dithianes) were found to undergo an intramolecular [2+2] photocycloaddition under visible‐light irradiation (λ=405 nm) in the presence of a Brønsted acid (7.5–10 mol %). Key to the success of the reaction is presumably the formation of colored thionium ions, whic...
