A UV-light-driven strategy for the construction of quinazolinone frameworks under photocatalyst-free conditions is developed. 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.

Key words: UV-light, photocatalyst-free, quinazolinone
