Toward the Briarane Core via 1,3-Dipolar Cycloaddition
Organic LettersThe complete C20 framework of brianthein W was established, featuring hydroboration/allylation, to provide the C1-C2 quaternary/tertiary stereoarray with excellent stereocontrol. Intramolecular nitrile oxide cycloaddition (INOC) was adopted as the key transformation to establish the trans-fused 6/10-bicyclic ring system.

New Briarane Stecholide Diterpenes from the Indonesian Gorgonian Briareum sp.
Journal of Natural Products, 1998The Indonesian gorgonian Briareum sp. has afforded two new briarane stecholide diterpenes: 2,9-diacetyl-2-debutyrylstecholide H (1) and 13-dehydroxystecholide J (2), the semisynthetic 2beta-acetoxy-2-(debutyryloxy)stecholide E acetate (3), which was isolated as a natural product for the first time, along with the known compounds stecholides I-M (4-8 ...

Fragilide B: A Novel Briarane-Type Diterpenoid with a S-cis Diene Moiety
Bulletin of the Chemical Society of Japan, 2007Abstract A novel chlorinated briarane derivative, fragilide B (1), was isolated from the Formosan gorgonian coral Junceella fragilis. Fragilide B (1) possesses a s-cis diene moiety in the structure. The structure of 1 was elucidated by interpretation of spectral data and further supported by molecular mechanics calculations.
