A photocatalytic CTC strategy for hydroarylation of both activated and unactivated alkenes via single-electron reduction using thiolate as a catalytic electron donor enables the synthesis of various polycyclic heterocycle molecules from N-arylacrylamides, N-methacryloyl benzamides, and alkenyl-substituted quinazolinones.
