摘要

Nanocrystalline CuFe _(2) O _(4) catalyzed one pot three component synthesis of chromeno[4,3- b ]pyrrol-4(1 H )-one derivatives has been achieved in aqueous media. The reaction between the essential building blocks (amine, glyoxal monohydrate and 4-aminocoumarin) has been performed at low catalyst loading, leading to a high yield of the desired heterocyclic scaffold. CuFe _(2) O _(4) magnetic nanoparticles were prepared by a simple and effective citric acid complex method and characterized by using XRD, FT-IR, EDX and TEM and HRTEM images. The easy recovery and reusability of the catalyst and operational simplicity of the process makes the protocol attractive, sustainable, and economic.
