A Direct Palladium‐Catalyzed Route to Selectively Substituted Carbazoles through Sequential CC and CN Bond Formation: Synthesis of Carbazomycin A

Abstract The present paper offers a synthetically simple one‐pot procedure for the catalytic preparation of the biologically interesting class of carbazoles. The new procedure is based on the combined catalysis of palladium and norbornene starting from o‐substituted iodoarenes and N‐sulfonylated or N‐acetylated o‐bromoanilines. A well‐known member of this class, carbazomycin A, has been successfully prepared.
