New xenia diterpenes isolated from the soft coral, xenia florida
Seven new xenia diterpenes have been isolated from the soft coral, Xenia florida. Four of them possess a bicyclic [4.3.1] ring system. The three others, which contained a cyclononane skeleton with an epoxide, seem to be precursors for diterpenes with a bicyclic [4.3. 1] ring system.
