A trifluoromethylation cyclization of unactivated alkenes attached to quinazolinone scaffolds is demonstrated under visible light photocatalysis using readily available and inexpensive trifluoroacetic acid and anhydride, without the need for strong oxidants. A wide substrate range and cyclization to 5- and 6-membered rings has been demonstrated in 44–82 % yields.
