title: Chlorinated briarane diterpenoids from the sea whip gorgonian corals Junceella fragilis and Ellisella robusta (Ellisellidae).
abstract: A new chlorinated briarane, fragilide J (1), has been isolated from the sea whip gorgonian coral Junceella fragilis. In addition, the sea whip gorgonian coral Ellisella robusta yielded two chlorinated briaranes, including a new compound, robustolide L (2), and a known metabolite, robustolide H (3). The structures of these compounds were determined using spectroscopic methods. The structure, including the absolute configuration of 3, was further confirmed by X-ray data analysis for the first time.
