Elaboration of the perhydroazulene ring system formed by the intramolecularcycloaddition of a dienyl-substituted 3-oxidopyrylium has generated key intermediates used in the total synthesis of the α- and β-series of the copaene and ylangene sesquiterpene hydrocarbons. During the synthesis of the β-series of compounds selective protection of an olefinic bond was achieved by thiol addition; protection
