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