Green chemistry is one of the most important routes for the synthesis of heterocyclic compounds. In this regard, the synthesis of 2-thioxoquinazolinone derivatives was achieved by condensation of versatile materials including isatoic anhydride, amine and potassium thiocyanate in the green medium of water. This convenient and ef?cient method affords the desired products with good to excellent yields.

A new and efficient synthetic process has been developed for preparation of 2-thioxoquinazolinone and quinazolinobenzothiazinedione derivatives. The related products were synthesized through reaction of isatoic anhydride, amines/anthranilic acids, and carbon disulfide (CS2) in the presence of potassium hydroxide in ethanol at reflux.
