Rhodium‐Catalyzed Intramolecular Cyclization of Naphthol‐ or Phenol‐Linked 1,6‐Enynes Through the Cleavage and Formation of sp2 CO Bonds

Ein kationischer Rhodium(I)-Binap-Komplex katalysiert die intramolekularen Cyclisierungen von Naphthol- oder Phenol-verknüpften 1,6-Eninen zu Vinylnaphtho- oder Vinylbenzofuranen und Vinylnaphtho- oder Vinylbenzopyranen unter Bruch und erneuter Bildung von C(sp2)-O-Bindungen. Mechanistischen Studien zufolge kommt es dabei zu einer β-Sauerstoff-Eliminierung aus intermediären kationischen Rhodacyclen.
