A tandem anionic 5-exo-dig cyclization/Claisen rearrangement sequence was used to effect a facile, “one-pot” conversion of an appropriately substituted 4-alkyn-1-ol to the tetracyclic carbon core structure of phorbol. The synthesis was conducted using readily available nonracemic starting materials to provide the target structure as a single enantiomer in high chemical yield.
