Abstract

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.

Keywords: cycloaddition isatin N,N′‑Cyclic Azomethine Imines heterocycles 1,3-Dipolar
