title: Preparation of phenalenes and hydronaphthacenes through tandem alkyne Fischer-carbene complex coupling and inter- or intramolecular Diels-Alder reactions.
abstract: The rapid construction of phenalenes through the reaction of 8-alkynyltetralones with Fischer carbine complexes followed by either inter- or an intramolecular Diels-Alder reaction is presented. As a showcase of the synthetic utility of this process, the rapid construction of polycyclic ring systems containing the tetracycline core has been demonstrated through an iterative application of this reaction sequence.
