title: Redox-neutral indole annulation cascades.
abstract: Aminobenzaldehydes react with indoles in an unprecedented cascade reaction. This acid-catalyzed redox-neutral annulation proceeds via a condensation/1,5-hydride shift/ring-closure sequence. Polycyclic azepinoindoles and related compounds are obtained in a single step with good to excellent yields.
