Abstract


An efficient synthesis of 3-aryl-2-cyclohexylamino-6,7-dihydro-1H-indole-4(5H)-ones using ferric perchlorate as the catalyst via four-component reaction between cyclohexylisocyanide, an aldehyde, a cyclic 1,3-dicarbonyl compound and ammonium acetate in acetonitrile is described.

Key Words: cyclohexylisocyanide, cyclic 1,3-dicarbonyl compound, multi-component reaction;1H-Indole-4(5H)-ones.
