Abstract: | A simple and efficient procedure has been developed for the one‐pot synthesis of 3,4‐dihydroquinazolin‐4‐ones from anthranilic acids, ortho esters and amines using a catalytic amount of iodine under solvent‐free conditions to afford the corresponding products in excellent yields. The direct use of commercially available catalyst, mild and solvent‐free reaction conditions, short reaction time, easy workup and excellent yields are the advantages of the present protocol. |
