A visible-light-driven, Brønsted-Lowry acids-promoted cascade cyclization between 1,3-enynes and 4-acyl-1,4- dihydropyridines (4-acyl-DHPs) has been established for the efficient synthesis of azaarene-functionalized polysubstituted furans. This metal-free transformation proceeds under mild reaction conditions and exhibits a broad substrate scope, encom- passing complex drug-derived enynes and diverse acyl radical precursors. Mechanistic investigations support a reaction pathway involving a radical-anionic-protonation sequence, including acyl radical addition, allene formation, and Brønsted- Lowry acids-facilitated cycloisomerization. The methodology offers a modular and environmentally benign route to azaarene- containing, densely functionalized furans with excellent functional group compatibility.

Key words: visible light, photoreaction, poly-substituted furan, cascade reaction, 1,3-eneynes
