1-naphthylamine, and 2-halobenzyl bromides is reported. A variety of tricyclic, tetracyclic, and pentacyclic sultams have been prepared via palladium-catalyzed, ligand-free intramolecularcyclization. Detailed mechanistic studies of the reaction pathway are also described. cyclization - palladium acetate - sulfonamides - sultams
