cyclohexanone-fused 2-(3-pyrrolyl)-2-cyanoacetamides, the condensation products of enamines, arylglyoxals, and malononitrile, are converted into highly substituted benzo[a]carbazoles through a one-step thermal cyclization and palladium-catalyzed aromatization. The biologically important indoleacetic acid derivatives are also obtained in good yields from the hydrolysis and aromatization of the same cyanoacetamides.
