Alkene–Arene meta Photocycloadditions with a Four‐Carbon‐Atom Tether: Efficient Approach toward the Polycyclic Ring Systems of Aphidicolin and Stemodinone

Abstract: Die Kette ist geschlossen! Die Kondensation des sechsgliedrigen Rings an die C4‐Kette des Substrats 1 eröffnet einen effizienten Zugang zu den polycyclischen Ringsystemen der Naturstoffe Aphidicolin und Stemodinon. Die Reaktion ist insofern einzigartig, als in einem intramolekularen System bevorzugt das Produkt entsteht, das sich von einem endo‐Exciplex ableitet (exo:endo 2:3=1.0:1.2).

“…The intramolecular reaction is suitable for the synthesis of complex structures, such as those depicted in Scheme 9.49, where [3 þ 2]-photocycloaddition leads to structures which resemble natural products (aphidicoline and stemoclinone). An interaction of the arene singlet excited state with the alkene ground state gives rise to the meta adduct [83,84]. The synthesis of a variety of organic compounds containing six-membered (and larger) rings can be achieved using photochemical reactions as the key step.…”
