2,3-Dimethylindole is easily converted intoN-benzoyl-2,3-dibromo methylindole, the latter upon treatment withsodium iodide in DMF in the presence of a suitable dienophilefurnishes a carbozole derivative.

A direct one-pot approach to the synthesis of carbazoles (mono-, di-, and trisubstituted) and α-carbolines from readily available indoles or 7-azaindoles and alkenes is described. Based on mechanistic studies, the tandem reaction follows the sequence: palladium-catalyzed regioselective C-3 alkenylation/palladium-catalyzed C-2 alkenylation/thermal electrocyclization.
