Alkenyl aziridines can be successfully arylated in a three-component coupling triggered by in situ generated benzyne with a simple copper catalyst (CuI-PPH3), without the need of any palladium salts. The corresponding allylic amines can be obtained with good to high regioselectivity in mild reaction conditions with a variety of cyclic and acyclic alkenyl aziridines . A new domino reaction with ethyl propiolate to give tetrahydrophenanthridine was also found.
