A New Series of Sesquiterpenoids From a Gorgonian

A new series of sesquiterpenoids containing a 2,2,7-trimethyl-4-(1-methylethyl )indan skeleton have been isolated from an unnamed Primnoeides sp., a gorgonian found in coastal New Zealand waters. The structures of these sesquiterpenoids have been formulated on the basis of spectral and chemical evidence, together with an X-ray structure determination of one of the new compounds.
