title: Xenibellols A and B, new diterpenoids from the formosan soft coral Xenia umbellata.
abstract: Xenibellols A (1) and B (2), possessing an unprecedented diterpenoid skeleton, were isolated from the soft coral Xenia umbellata. The structures of xenibellols A and B were established by extensive analysis of spectroscopic data.
