本文报道了一种在无外加光催化剂条件下构建喹唑啉酮骨架的紫外光驱动策略。廉价易得的叔丁基过氧化氢(TBHP)作为自由基引发剂,在紫外光照射下促进邻氨基苯甲酰胺与芳香醛之间的自由基参与偶联/环化串联反应,从而高效获得一系列喹唑啉酮衍生物。该方法具有操作简便、原料来源广泛且易得、转化效率良好等优点,同时避免了过渡金属和外加光催化剂的使用。因此,该方法为喹唑啉酮骨架的绿色可持续合成提供了一种有价值的补充途径;喹唑啉酮骨架也是一类具有药物相关意义的重要结构单元。

Herein, we report a UV-light-driven strategy for the construction of quinazolinone frameworks under photocatalyst-free conditions. Readily available and inexpensive tert-butyl hydroperoxide (TBHP) serves as a radical initiator to promote a radical-involved coupling/cyclization cascade between o-aminobenzamides and aryl aldehydes under UV irradiation, affording a range of quinazolinone derivatives efficiently. This protocol features operational simplicity, high feedstock accessibility, and good conversion efficiency, while avoiding the use of transition metals and external photocatalysts. As such, it provides a valuable complementary approach to the green and sustainable synthesis of quinazolinone scaffolds, an important class of pharmaceutical relevant scaffolds.
