An efficient metal‐free, (NH4)2S2O8 mediated intramolecular oxidative cyclization for the construction of fused polycyclic quinazolinone derivatives under mild conditions was disclosed. This method provides an efficient and facile approach to the synthesis of polycyclic quinazolinone derivatives (> 40 examples), as well as the natural products tryptanthrin, rutaecarpine, and their analogues.
