A simple and efficient synthesis of new 6-arylimino-6H-indolo[2,1-b] quinazolin-12-ones under microwave Irradiation

摘要

A ring opening and selective reaction of isatoic anhydride with isatin-3-imine in the presence of catalytic amount of KF-Al_2O_3,a reusable catalyst,to yield a novel series of 6-arylimino-6H-indolo [2,1-b] quinazolin-12-one under microwave irradiation,is described.
