Herein, this work describes a photoinduced visible light-mediated radical cyclization for constructing dihydrobenzofuran (DHB) scaffolds. Notably, this cascade photochemical process is tolerable with various aromatic aldehydes and diverse alkynylarylethers and proceeds via an intramolecular 1,5-hydrogen atom transfer (HAT) pathway. Significantly, acyl C–H activation under mild conditions has been
