Abstract
Novel pyrazolopyridine-spiroindolinones were prepared by the three-component reaction of 5-aminopyrazoles, isatin, and cyclic β-diketones in aqueous media and catalyzed by p-TSA. This protocol provides a simple one-step procedure with the advantages of easy work-up, mild reaction conditions and environmentally benign.
