Steroidal compounds from the Caribbean octocoral Eunicea laciniata.
A previously isolated trihydroxy-gorgosterol derivative (2), a new gorgosterol (3), and the known sterol cholestane-3beta,5alpha, 6beta-triol are reported from the Caribbean octocoral Eunicea laciniata collected off northeast Venezuela. Using high-resolution 2D NMR techniques, the total structural assignment and detailed stereochemistry of 2 is presented for the first time and the full structure of 3 advanced.
