Ruthenium‐Catalyzed Coupling of Oxabenzonorbornadienes with Alkynes Bearing a Propargylic Oxygen Atom: Access to Stereodefined Benzonorcaradienes

Abstract

Stereodefiniert: Die Titelreaktion bietet eine atomökonomische Route zu Benzonorcaradienen. Die Diastereoselektivität der Kupplung hängt von der Struktur des Alkens ab: Unsubstituierte bicyclische Alkene liefern ausschließlich exo-Benzonorcaradiene (siehe Schema), während bicyclische Alkene mit Substituenten an den Brückenkopfpositionen zu endo-Benzonorcaradienen führen.
