Cyano-N-(2-oxo-1,2-dihydroindol-3-ylidene)acetohydrazide was prepared by condensation of isatin with cyanoaceto-hydrazide in refluxing 1,4-dioxane. Subsequent reaction with a variety of electrophilic and nucleophilic reagents afforded novel heterocyclic compounds and spirooxoindoles. The IR, 1H NMR and mass spectra of all the synthesised compounds are discussed.
