Six‐membered ring fused furans containing a tetrasubstituted tertiary carbon were prepared in an unprecedented one‐pot BODIPY‐catalyzed domino photooxygenation/reduction process. A series of functionalized furans was synthesized from readily available 2‐alkenylphenols and mechanistic studies were performed to account for the domino photosensitized oxygenation.

A multicatalytic photooxygenation of substituted phenols in the presence of rose bengal and cesium carbonate under green LED light is reported. This transformation enabled the introduction of both atoms of singlet oxygen and led to the one-pot synthesis of epoxyquinols in a stereoselective way.
