Quinazolines are found in numerous commercially available drugs. Herein, we report a catalyst-free photochemical approach for the direct alkylation of these N -heterocycles under mild conditions. Additionally, late-stage functionalization of bioactive natural products—including caffeine, quinine derivative and flavone—was successfully achieved. Notably, the …
