Solid‐State Synthesis of 4‐[(Indol‐3‐yl)‐arylmethyl]‐1‐phenyl‐3‐methyl‐5‐pyrazolones by Catalysis of Molecular Iodine

Abstract

4‐[(Indol‐3‐yl)‐arylmethyl]‐1‐phenyl‐3‐methyl‐5‐pyrazolones could be smoothly and effectively obtained in good yields through the iodine‐catalyzed reactions under solid‐state conditions at room tempertaure. The three‐component approach in a one‐pot procedure was reported for the first time. A possible mechanism was suggested to elucidate the remarkable reaction selectivities.
