Palladium-catalyzed intramolecular Heck tandem cyclization reactions were developed. With palladium iodide as a catalyst and 4-(dimethylamino)triphenylphosphine as a ligand, 3-substituted indoleamide derivatives were converted to bridged N-heterocyclic products in good yields under simple reaction conditions. The tandem reactions are featured by efficient construction of fused ring compounds in one pot and good functional group compatibility.

Key words: palladium catalyst, intramolecular Heck cyclization, bridged N-heterocyclic compound
