Angular tricyclic compounds as intermediates for total synthesis of magellanine were synthesized by stereoselective Ireland–Claisen rearrangement and intramolecular Pauson–Khand reaction of exo-methylenecyclohexylalkynes. Interestingly, remarkably different reactivity was observed in the Pauson–Khand reaction of cis- and trans-disubstituted exo-methylenecyclohexylalkynes.
