In this paper a unique approach to the synthesis of polycyclic ring systems is disclosed. The approach features an intermolecular Diels-Alderreaction followed by an intramolecular Diels-Alderreaction where the regiochemistry of addition is controlled by substituents on the bisdiene and bisdienophile. This methodology has been applied to the synthesis of the fluorenone ring system. An efficient convergent
