studies toward the synthesis of a number of guanacastepenes. The synthetic strategy relies on the use of cyclohexyne in a cycloinsertion reaction to rapidly construct the guanacastepene core. Isolation of a cyclobutenol as intermediate in the cyclohexynecycloinsertion provided us with the possibility to study further the reactivity of this metastable compound, and we uncovered novel rearrangements and
