A simple and eco-friendly method for the preparation of 1,5-diaryl-3-(arylamino)-lH-pyrrol-2(5H)-ones via the cyclo-condensation reaction of aldehydes, amines and ethyl pyruvate in the presence of silica supported ferric chlo- ride (SiO2-FeCl3) as reusable heterogeneous catalyst is described. The present methodology offers several advantages such as excellent yields, simple procedure and short reaction times. 展开更多
