Rh-Catalyzed [3 + 2] Cascade Annulation of Aromatic Acids with Oxabicyclic Alkenes: Direct Access to Planar Benzo[ a ]fluorenones

Abstract A rhodium-catalyzed [3 + 2] annulation of aromatic acids and 7-oxabenzonorbornadienes has been developed, enabling a facile one-step synthesis of planar π-conjugated polycyclic benzo[a]fluorenone featuring an ordered herringbone packing motif with slipped stacking in mod...
