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.
使用容易获得且廉价的三氟乙酸和酸酐,在可见光光催化下证明了连接到喹唑啉酮支架上的未活化烯烃的三氟甲基化环化,而不需要强氧化剂。广泛的底物范围和 5 元环和 6 元环的环化已被证明具有 44-82% 的产率。
