A simple and efficient one-pot synthetic approach was used for the preparation of biologically interesting spirooxindole derivatives by means of three-component reactions of isatins, malononitrile, and 1,3-dicarbonyl compounds catalyzed by ethylenediamine diacetate (EDDA) in an aqueous medium. This method is of great value because of its environmentally benign character, high yield, and easy handling
