Structure Elucidation of Briarane Diterpenoids Using Molecular Mechanics Calculations

Bulletin of the Chemical Society of Japan, 2006
Abstract A combination of NMR analysis and molecular mechanics calculations has succeeded in the determination of the stereostructure of flexible briarane diterpenoids. The molecular mechanics calculations disclosed the multi-conformational nature of the briarane diterpenoids and gave a successful reproduction of the observed 3J coupling

Four New Briarane Diterpenoids from the Gorgonian Coral Junceella fragilis

Helvetica Chimica Acta, 2007
AbstractChemical investigation of the gorgonian coral Junceella fragilis, collected by scuba diving in Taiwan, resulted in the isolation of four new briarane‐type diterpenoids, frajunolides A–D (1–4), along with three known briaranes. Their structures were elucidated on the basis of spectroscopic studies, especially 1‐ and 2D‐NMR as well as HR‐MS ...

Briarane-Type Diterpenes from a Closed-System Cultured Soft Coral Briareum stechei.

Phytochemistry
In this study, by using untargeted LC-MS/MS-based multi-informative molecular networking, 12 briarane diterpenoids were isolated from a closed-system cultured soft coral Briareum stechei.

Chlorinated briarane-type diterpenoids from the gorgonian coral Ellisella robusta (Ellisellidae)

Tetrahedron, 2007
Abstract Four chlorinated metabolites featuring briarane carbon skeletons have been isolated from the gorgonian coral Ellisella robusta, which was collected off the coast of southern Taiwan: two new natural products, robustolides D (1) and E (2), and two known metabolites, robustolides F (3) and G (4).

Fragilide B: A Novel Briarane-Type Diterpenoid with a S-cis Diene Moiety

Bulletin of the Chemical Society of Japan, 2007
Abstract 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.
