title: Intramolecular trans-Dicarbofunctionalization of Alkynes by a Formal anti-Carbopalladation/Stille Cascade.
abstract: An intramolecular Pd-catalyzed trans-dicarbofunctionalization of internal alkynes using aryl bromides and aryl stannanes is presented. Tetrasubstituted double bonds embedded in an oligocyclic ring system are obtained in a regio- and diastereoselective fashion. The transformation features a broad substrate scope and functional-group tolerance.
