The development of a versatile new one pot, catalyst free, multicomponent-tandem strategy for assembly of spirooxindole-indazolones and spirooxindole-pyrazolines is described. The reported protocol includes several advantages like environmental friendliness, cost effectiveness, high atom economy, short reaction times and high yields. The reported method is the first green synthesis of spirooxindole-indazolones and spirooxindole-pyrazolines.
