Synthesis of pyrazolopyridines catalyzed by nano-CdZr۴(PO۴)۶ as a reusable catalyst

چکیده مقاله

A simple and efficient method for the preparation of pyrazolopyridines by a multicomponent reaction of ethyl acetoacetate, an aldehyde, hydrazine and ammonium acetate using nano-CdZr4(PO4)6 as an efficient catalyst is presented. The main advantages of this protocol include short reaction times, practical simplicity, high yields, recyclable catalysts and applicability to wide range of substrates.
