AB  - Triquinanes and propellanes represent a class of natural products. These specifically condensed carbocyclic structures are still the object of ongoing research including the development of various synthetic methods. Among these methods photochemical ring closure reactions such as radical ion cyclization reactions were used.
Tricyclic cyclopropyl ketones are suitable starting materials for C-C bond cleavage under reductive PET conditions to keto radicals. In this contribution we will present some examples of photoinduced cyclization processes of bicyclo[n.3.0]alkanone derivatives with an unsaturated side chain. These photoinduced cyclization reactions lead to polycyclic compounds of the polyquinane family with high regio-, stereoselectivity and yields.
