Making azacycles: The [Ir(cod)Cl}2]/L complex efficiently catalyzes the tandemallylicvinylation and asymmetric allylicamination of (E)‐2 with ortho‐amino styrene derivatives 1 to afford the title compounds 3 with excellent enantioselectivity. cod=1,5‐cyclooctadiene, DABCO=1,4‐diazabicyclo[2.2.2]octane.
