摘要：
In this paper, a multicomponent green rapid method for synthesis of pyranopyrazoles is reported using NiWO4 in water in 15 min. Environment friendly features such as energy efficiency, aqueous medium, no hazardous solvent, no chromatography, in addition to the short reaction time, catalyst reusability and substrate tolerance without affecting yield proves the near perfectness of this method for synthesis of medicinally important pyranopyrazoles. NiWO4, ZnWO4 and CuWO4 have been synthesized using extract of plant Phyllantus amarus. The prepared catalysts have been characterized by XRD, EDX and SEM.
