  Synthesis of Tricyclic Heterocycles via a Tandem Aryl Alkylation/Heck Coupling Sequence

  摘要：

  A norbornene-mediated palladium-catalyzed sequence is described in which two alkyl-aryl bonds and one alkenyl-aryl bond are formed in one pot with use of microwave irradiation. A variety of symmetrical and unsymmetrical oxygen-, nitrogen-, silicon-, and sulfur-containing tricyclic heterocycles were synthesized from a Heck acceptor and an aryl iodide containing two tethered alkyl halides. This approach was further applied to the synthesis of a tricyclic mescaline analogue.

  A norbornene-mediated palladium-catalyzed tandem alkylation/cyanation sequence is described in which an alkyl-aryl bond and a nitrile-aryl bond are formed in one pot. A variety of sterically hindered, five-, six-, and seven-membered ring benzonitriles were synthesized in good yields from easily accessible starting materials.
