Action of Hydrazines on 2-(2-Oxindolin-3-ylidene)malononitrile, (E,Z)-Ethyl 2-cyano-2-(2-oxindolin-3-ylidene)acetate and Isatin-β-thiosemicarbazone as a Source of Spiro Indoline-pyrazole Systems

2-(2-Oxindolin-3-ylidene)malononitrile (1a) or (E,Z)-ethyl 2-cyano-2-(2-oxindolin-3-ylidene)acetate (1b) or isatin-β-thiosemicarbazone (1c) undergoes reactions with prototype hydrazine hydrate itself and some of its simple congeners to give hydrazone derivatives bearing indoline-2-one moiety (2). The hydrazone derivatives (2) when heated with acetyl acetone or ethyl acetoacetate in dry pyridine afforded the spiro indoline derivatives (3a, 3b). Also, cinnoline derivative (9) is obtained by action of hydrazine hydrate on the N-acetyl derivative of (6a). The structures of the newly synthesized compounds were evaluated by IR, 1H-NMR spectroscopy, mass spectra and elemental analyses.

Schiff bases and hydrazones of substituted isatins have been prepared by reacting isatin and the appropriate aromatic primary amine l hydrazines and characterized by spectral and elementary analysis. The compounds have been screened for analgesic, antiinflammatory and antipyretic activity. 3[(4-Bromo phenylidene)-1-amino] isatin is the only compound to exhibit all the activities. 3[(4-Bromo phenylidene)-1-amino] isatin and 3[(4- Bromo phenylidene)-1-amino]-5-methyl isatin possesses analgesic activity equipotent to paracetamol. 3(4-Phenylhydrazino) isatin and 3(thiosemicarbazino) isatin exhibit marked reduction of acetic acid induced inflammation. 3[(4-Methyl phenylidene)-1-amino] isatin at 200 mg/kg exhibits pronounced antipyretic activity comparable to paracetamol.
