A stereocontrolled synthesis of the ABCrings of solanoeclepin A has been achieved. The seven-membered ring B was synthesized by an intramolecular Prins-ene reaction between an aldehyde and an enyne-dicobalthexacarbonyl complex. The acetylene in this synthesis plays multiple roles: to join the A and C rings, to allow stereoselective cyclization via dicobalthexacarbonyl complexation, and to facilitate
