Palladium(0)-catalyzed reactions between allenamides or and aryl iodides/bromides / provide an easy access to δ-carbolines or benzofuro[3,2-]pyridines . The reaction constitutes a fast intermolecular assembly that takes place in one pot, and the choice of the phosphine ligand is critical for success. A plausible reaction mechanism is proposed. The reaction is amenable to the synthesis of bis-heteroannulated products.
