Clavulones, new type of prostanoids from the stolonifer clavularia viridis quoy and gaimard

Abstract Three new prostanoids, clavulone I( 1 ), II( 2 ) and III( 3 ), were isolated from the Japanese Stolonifer Claularia viridis Quoy and Gaimard. The structures of these prostanoids were determined on the basis of spectral data and chemical reactions.

Absolute stereochemistry of new prostanoids clavulone I, II and III, from Clavularia viridis Quoy and Gaimard

Abstract Absolute configurations at the C-4 and -12 positions of a new type of prostanoids clavulone I ( 1 ), II ( 2 ) and III ( 3 ), isolated from Clavularia viridis Quoy and Gaimard, have been elucidated on the basis of chemical and spectral evidence.

Novel C-20-oxygenated prostanoids, 20-acetoxyclavulones, from the stolonifer clavularia viridis quoy and gaimard

Three new marine prostanoids having an acetoxyl group at a C-20 position, 1, 2 and 3, were isolated from the Japanese Stolonifer Clavularia viridis Quoy and Gaimard. Their structures were eluciated by spectroscopic methods.

Lemnalol, a new sesquiterpenoid from the soft coral Verseveldt

Abstract The structure and absolute stereochemistry of lemnalol (1), a new ylangene-type sesquiterpenoid isolated from the soft coral Lemnalia tenuis Verseveldt, has been established by spectroscopic, chemical, and x-ray crystallographic analyses.
