Patagonicol: a diterpenoid from the Chinese soft coral Alcyonium patagonicum.

Patagonicol [1], a diterpenoid with a eunicellin skeleton, was isolated from the soft coral Alcyonium patagonicum. The structure of 1 was determined by X-ray diffraction, and detailed 1H and 13C assignments were made via 1D and 2D nmr experiments.
