Isolated from a New Zealand podocarp in 1997, waihoensene is a tetracyclic diterpene with four contiguous quaternary carbon centers. Lee and co-workers report the first total synthesis of the title compound by employing a trimethylenemethane cycloaddition.



Condensation of aldehyde F with tosylhydrazide followed by elimination, afforded di­azoalkane G, which underwent the key tandem cycloaddition to afford tetracycle J. Four more steps completed the synthesis of (±)-waihoensene.
