The structure of eunicillin (89), a carbobicyclic diterpenoid isolated from the Mediterranean gorgonian Eunicella stricta, was reported in 1968 (1). At that time chlorine-containing diterpenoids had been dis- covered in the gorgonian Briareum asbestinum (2, 3), but it was not until 1977 that the structure of the first briaran, briarein A (211), was resolved by X-ray analysis (4). The first trinervitane diterpenoid (26), which was isolated from Trinervitermes termites, was reported in 1976 (5).
