Abstract
3-Aryl-4(3H)-quinazolinones were synthesized efficiently by the three component one-pot cyclocondensation of anthranilic acid, ortho esters, and anilines in the presence of Ce(CH3SO3)3·2H2O at room temperature under solvent-free conditions. This method offers several advantages, such as a simple procedure, mild reaction conditions, short reaction time, and reusability of the catalyst.
