A metal-free and efficient visible-light induced cascade cyclization of alkyne-tethered cyclohexadienones with selenosulfonates has been developed for the synthesis of 3-sulfonyl-5-selanyl-4a,5-dihydro-2H-chromen-6(8aH)-one in good to excellent yields, forming three new stereocenters and introducing both sulfone and selenyl groups simultaneously.
