transformed into the Grignard reagent 6 or the cuprates 7 and 8. Reagents 6–8 are useful for effecting methylenecyclopentaneannulations, as illustrated by the conversions of 31–36 into 43–48, respectively. This novel annulation method played a key role in a total synthesis of the sesquiterpenoid (±)-Δ9(12)-capnellene (55).
