CuCO3 catalyzed 1, 3-dipolar cycloaddition of isatin N,N′‑cyclic azomethine imine has been developed.  Biologically active heterocyclic spiro[indoline-3,1'-pyrazolo[1,2-a]pyrazoles] were prepared as single regioisomers in good yields and functional group compatibility.

The first example of the cycloaddition of in situ-generated azomethine imine under microwave conditions is described. The reaction of 6-aryl-1,5-diazabicyclo[3.1.0]hexanes with 1,3-diphenylprop-2-en-1-ones proceeds regio- and stereoselectively giving mostly good yields of the corresponding perhydropyrazolopyrazoles. The products of the reaction undergo cycloreversion under the reaction conditions.
