Synthesis of tricyclic ketones with sesquiterpene skeletons by acid- catalyzed rearrangement of β-monocyclofarnesol

Starting from dihydro-β-ionone (6) a mixture of three tricyclic ketones with sesquiterpene skeletons 14,15, and 16 was prepared by Wittig-Horner reaction with triethyl phosphonoacetate, Red-Al reduction, acid-catalyzed rearrangement of the resulting β-mon
