An organophotoredox-catalyzed cascade reaction involving CC σ-bond cleavage, CC bond formation, and a subsequent Truce-Smiles rearrangement has been developed using spiro-dihydroquinazolinones and activated alkenes. This aromaticity-driven deconstructive functionalization strategy efficiently yields valuable quinazolinone-containing long-chain amides bearing an α-all-carbon quaternary center. Mild redox-neutral conditions, good functional group compatibility and high atom economy are the noteworthy features of this …
