A selective three-component 1,2-sulfonyl etherification of aryl 1,3-dienes enabled by copper catalysis to afford biologically interesting alkenyl 1,2-sulfone ether derivatives through C–S and C–O bond formation is described. The protocol proceeds with the sulfonyl chloride alcohols under simple, mild, base-free conditions, providing a straightforward route sulfonylated allyl compounds broad functional group tolerance excellent chemo- regioselectivity. Mechanistic studies indicate that alkene difunctionalization includes key copper-mediated single-electron transfer process.

Abstract Radical‐involved multicomponent difunctionalization of 1,3‐dienes has recently emerged as a promising strategy for rapid synthesis valuable allylic compounds in one‐pot operation. However, the expansion radical scope and enantiocontrol remain two major challenges. Herein, we describe an unprecedented photoinduced copper‐catalyzed highly enantioselective three‐component 1,2‐azidooxygenation with readily available azidobenziodazolone reagent carboxylic acids. This mild protocol exhibits broad substrate scope, high functional group tolerance, exceptional control over chemo‐, regio‐ enantioselectivity, providing practical access to diverse azidated chiral esters. Mechanistic studies imply that copper complex is implicated bifunctional catalyst both photoredox catalyzed azidyl generation C−O cross‐coupling.

Abstract With Ag/g‐C 3 N 4 semiconductor as the heterogeneous photocatalyst, visible light promoted synthesis of unsymmetric diaryl chalcogenides could be achieved under additive‐free and mild conditions. A series were generated in good to excellent yields with high functional group tolerance. The photocatalyst is easily recovered from reaction mixture reused at least 5 times, opening way for larger‐scale industrial applications this type photocatalytic bond‐forming reactions.
