The structure and stereochemistry of phorbol, a novel tetracyclic diterpene containing a reactive hydroxycyclopropyl carbinol system, is discussed. It undergoes protonation at the homoallylic 12-hydroxy-group and gives crotophorbolone (an isopropenyl cyclohexanone) and crotophorbolone K (a dimethyl cyclobutanone). With boron trifluoride–acetic acid, phorbol triacetate gives an acetoxy-isopropyl cyclohexanone
