Microwave-Induced One - Pot Synthesis of some new Spiro [Indoline-3,2′-Thiazolidine]-2,4′<i>(1H)</i>-Diones and Bis [Spiro [Indoline -3,2′-Thiazolidine]-2,4′<i>(1H)</i>-Diones]

Abstract

Abstract The title compounds have been obtained thermally and under microwave irradiation by condensation of isatin, aromatic amines and mercaptoacetic acid in good to excellent yields without isolating the imine intermediates.
