An intramolecular cascade reaction consisting of a formal anti-carbopalladation terminated by the ring opening of a cyclopropanol unit is presented. The products, which involve tetrasubstituted alkene units embedded in an oligocyclic ring system, are generated in moderate to excellent yield. The opening of the cyclopropanol unit leads to a keto group in the gamma-position to the emerging double bond.
