Abstract
The efficient synthesis of eleven tetrahydrodipyrazolopyridines (two of which are novel) has been achieved by the multicomponent condensation reaction of ethyl acetoacetate, an araldehyde, hydrazine hydrate and ammonium acetate at room temperature in ethanol in the presence of nano-CuCr2O4. The key advantages of this process are good to high yields, short reaction times, practical simplicity, reusability of the catalyst and low catalyst loading.

Abstract
Preparation of a series of 3-cyano-2-(1 H-indol-3-yl)-6-(9-butylcarbazol-3-yl)pyridine derivatives through the one-pot four-component coupling of aromatic aldehydes, 1-(9-butylcarbazol-3-yl)ethanone, 3-(cyanoacetyl)indole and ammonium acetate is reported. All these compounds were obtained in good yield and their structures were confirmed by 1H NMR and IR spectroscopy and by elemental analysis.
