Survey of Briarane-Type Diterpenoids – Part IV
HETEROCYCLES, 2011 The structures, names, biological activities, and references of 137 briarane-type diterpenoids are summarized. All briaranes mentioned in this review article were obtained from various octocorals including the specimens belonging to the genus Briareum, Ellisella, Gorgonella, Junceella, Subergorgia, Renilla, and Pachyclavularia.

Marine Invertebrate Natural Products for Anti‐Inflammatory and Chronic Diseases
Evidence-Based Complementary and Alternative Medicine, Volume 2013, Issue 1, 2013., 2013 The marine environment represents a relatively available source of functional ingredients that can be applied to various aspects of food processing, storage, and fortification. Moreover, numerous marine invertebrates based compounds have biological activities and also interfere with the pathogenesis of diseases.

Briarenols C–E, New Polyoxygenated Briaranes from the Octocoral Briareum excavatum
Molecules, 2017 Three new polyoxygenated briarane diterpenoids, briarenols C–E (1–3), were isolated from the octocoral Briareum excavatum. The structures of briaranes 1–3 were elucidated by interpretation of spectroscopic data, and the methylenecyclohexane ring in 1 was

Torsional steering as friend and foe: development of a synthetic route to the briarane diterpenoid stereotetrad. [PDF]
Org Biomol Chem, 2017 Two synthetic routes to the briarane stereotetrad have been investigated. The first route employed a boron aldol reaction to establish the stereogenic all-carbon quaternary carbon (C1). In this case, it was found that torsional steering in the transition state led to the formation of the undesired configuration at this position.
