An environmentally benign approach for the synthesis of pyrazolophthalazinyl spirooxindoles has been developed with the help of a task-specific ionic liquid [DBU][AcOH], which plays the dual role of catalyst as well as reaction medium. The advantages of this method include the use of green reaction conditions, no organic solvent, easy work-up, excellent yields and recyclability of the ionic liquid.

A direct and efficient approach for the preparation of pyrazolophthalazinyl spirooxindoles has been developed through one-pot three-component reaction of easily available isatin, malononitrile or cyanoacetic ester, and phthalhydrazide catalyzed by nickel chloride in polyethylene glycol 600. Desired products were obtained in high to excellent yields using a simple workup procedure.
