New pyrazolo [3,4-b]pyridine-5-spirocycloalkanedione derivatives were prepared via three-component reaction between 5-(4-R-benzylamino)pyrazoles, cyclic b-diketones and paraformaldehyde. The use of indandione as b-diketone resulted in the formation of two products, the pyrazolo[3,4-b]pyridine-5-spir
## Abstract magnified image New fused indeno[1,2β__b__]pyridine derivatives have been prepared in a multicomponent reaction from benzaldehydes, indanedione and the appropriate aminoheteroaryl compound. The simple methodology permitted the syntheses of a series of indeno[1,2β__b__]pyrazolo[4,3β__e_
