Described herein is a photoinduced copper-catalyzed 1,2-difunctionalization of 1,3-dienes. The selenium atom radical was generated by the visible light irradiation diselenides, triggering addition with 1,3-dienes to form allyl intermediate. Subsequent rapid Z/E isomerization allowed for thermodynamically favorable intermediate formation and enabled copper catalyzed stereoselective functionalization various nucleophiles.

A novel visible-light-induced sulfonylation cyclization to indole-fused medium-sized N-heterocycles was established under room temperature with biomass-derived 2-Me-THF as the solvent. This reaction proceeds in absence of external photocatalyst, additive, metal salts, and base. Broad substrate scope, good functional group compatibility, large-scale synthesis derivatization via iodination, nitration, chlorination, cyanation, selenylation demonstrate utility this protocol. radical route proposed based on inhibition experiments, visible-light irradiation on-off test, apparent quantum efficiency calculation, UV-vis absorption spectroscopic studies.
