Zirconium-promoted cyclization of the diene (1) resulted in the perhydroquinoline derivatives (2a) and (3a) in moderate yields. The intermediary zirconacycles can be converted into the iodinated products (2c) and (3c) by treatment with iodine, and into the tricyclic ketones (12) by treatment with carbon monoxide.
