Palladium‐Catalyzed Regioselective <i>peri</i>‐ and <i>ortho</i>‐Halogenation of 1‐Naphthaldehydes: Application to the Synthesis of Polycyclic Natural Product Skeletons
an imine formation was necessary to achieve C2-halogenation. The mechanism as well as the regioselectivity of the reaction were studied and the halogenated products were used in the synthesis of natural product skeletons.
