Live and let diene: A palladium(II)-catalyzed oxidative carbocyclization reaction of aza-enallenes provides access to potentially valuable heterocyclic dienes. In the presence of a dieneophile during the carbocyclization step, the products can react further in a one-pot cyclization/Diels–Alder sequence to give polycyclic products. BQ=para-benzoquinone.
