A versatile pathway for the synthesis of novel bis(quinazolinon‐4(1H)‐one) derivatives by one‐pot pseudo five‐component condensation of two molecules isatoic anhydrides, two molecules orthoesters, and diamines in high yields and short reaction time is described. The work‐up is easy, and the products...
