Cascade reactions: A modular assembly of azabicycles by using a cascadecyclization/Suzuki coupling/6π‐electrocyclization of bromoenynamides is reported (see scheme). The reaction offers a wide substituent scope on the bicyclic aminodiene products, which can be selectively oxidized as a general approach to aromatic azabicycles.
