We hereby report a visible light mediated alkyl sulfonylative cascade cyclization of alkynyl and dialkynyl cyclohexadienones via SO2 insertion. The protocol utilizes alkyl Hantzsch esters as the alkyl source and DABSO as the SO2 source with 4-CzIPN as the organophotocatalyst. A variety of dihydrochromenone derivatives were obtained in good yields under mild energy efficient conditions. Additionally, fluorescence quenching and control studies were carried out to probe the mechanism.
