The Lewis acid (borontrifluoride etherate) catalyzed novel synthesis of 2,4,6-trisubstituted-6H-1,3-oxazines is described here. Also, a new route towards an environmentally benign synthesis of the title compounds has been developed using montmorillonite K-10 clay as a catalyst under microwave irradiation (MWI). The procedure replaces the Lewis acid, and the products are obtained in a high yield and shorter reaction time.
