A biomimetic synthesis of briareolate ester B (3) from briareolate ester L (1) via the intermediate briareolate ester G (2) has been achieved through a unique transannular oxa-6π electrocyclization induced by UVA light. UVC irradiation of 3 triggered a rapid retro-6π electrocyclization to establish an unprecedented photochromic switch.

Absolute structures of new briarane diterpenoids from junceella fragilis
Journal of Natural Products, 1999Four new diterpenoids with the briarane skeleton, (-)-4-deacetyljunceellolide D (2), (+)-11alpha, 20alpha-epoxyjunceellolide D (3), (-)-11alpha, 20alpha-epoxy-4-deacetyljunceellolide D (4), and (-)-11alpha, 20alpha-epoxy-4-deacetoxyjunceellolide D (5), (+)-junceellolide A (6) [the antipodal derivative of the known (-)-junceellolide A], along with three

Survey of Briarane-related Diterpenoids — Part II
HETEROCYCLES, 2005The structures, names, biological activity, and references of sixty-six new briarane-related diterpenoids are described in this mini-review. All briaranes are obtained from Gorgonacea (genus Briareum, Erythropodium, Ellisella, and Junceella) and Pennatulacea (genus Cavernularia and Pteroeides). Some of these natural products showed potential biological

Survey of Briarane-Type Diterpenoids of Marine Origin
HETEROCYCLES, 2002The structures, names, biological activities, and references of two hundred ninety-nine marine original briarane-type metabolites are described and compiled in tabular form in this review. All briarane-type natural products are obtained from marine invertebrates, including various octocorals, a nudibranch, and a sponge.

A new antifungal briarane diterpenoid from the gorgonian Junceella juncea Pallas
Bioorganic & Medicinal Chemistry Letters, 2011A new 8-hydroxy briarane diterpenoid (compound 1) with antifungal activity was isolated along with known compounds (2-5) from the gorgonian coral Junceellajuncea. On the basis of spectroscopic data (1D and 2D NMR, MS), the structure of the compound 1 was established as (1S,2S,8S,9S,10S,11R,12R,14S,17R)-11,20-epoxy-14-(3-methylbutanoyl)-2,9,12 ...
