Juncin N, a new briarane-type diterpenoid from the gorgonian coral Junceella juncea

A new chlorinated briarane-type diterpenoid, juncin N (1), has been isolated from the gorgonian coral Junceella juncea. The structure, including the relative configuration of the new compound (1), was elucidated by the combination of extensive spectral data analysis, especially in 1 D and 2D NMR.

Excavatoids O and P, New 12-Hydroxybriaranes from the Octocoral Briareum excavatum

Two new 12-hydroxybriarane diterpenoids, designated as excavatoids O (1) and P (2), were isolated from the octocoral Briareum excavatum. The structures of briaranes 1 and 2 were established on the basis of extensive spectral data analysis. Excavatoid P (2) is the first metabolite which possesses a 6β -chlorine atom in briarane analogues.
