enones 9, 12–17, followed by base-promoted intramolecular alkylation of the resultant products, gives the (Z)-ethylidenecyclopentane annulation products 11, 18–23, respectively. This new annulation method is applied to the total synthesis of the opiopanane-type sesquiterpenoids 27, 28, and 38.

The epimeric sesquiterpene alcohols (14R)-β-oplopenol and (14S)-β-oplopenolwere obtained by LiAlH4 reduction of β-oplopenone. The complete 1H- and 13C-NMRassignments of these two new sesquiterpene alcohols have been made using 1D and 2DNMR techniques, including COSY, NOESY, HSQC, HMBC experiments.
