Today, the use of nano-catalysts has increased rapidly and has resulted in the development of several active and efficient nano-catalysts for various protocols. These systems have several advantages over conventional catalysts, such as superior activity, improved stability, environmentally safe disposal, high-performance and potential, increased efficiency of products, ease of separation and reuse ability. First part Quinazolins has significant attention because of their biological and pharmacological properties. Herein, we have investigated the catalyst activity of CoAl2O4 nano-particles for the synthesis of dihydroquinazoline derivatives in refluxing ethanol.
