ABSTRACT Green chemistry is one of the most important routes for the synthesis of heterocyclic compounds. In this regard, the synthesis of 2-thioxoquinazolinonederivatives was achieved by condensation of versatile materials including isatoic anhydride, amine and potassium thiocyanate in the green medium of water. This convenient and efficient method affords the desired products with good to excellent yields
Three component one-pot reaction for synthesis of 2-thioxoquinazolin-4(1H)-ones are given by the condensation of isatoic anhydride, primary amine and phenyl isothiocyanate by using KF/Al2O3 as a environmentally friendly catalyst.
