Seven new cytotoxic xenicane-type diterpenoids, 9-deoxyxeniloide-E (1), 9-deoxy-7,8-epoxyxeniloide-E (2), xeniolide-G (3), 9-deoxyxenialactol-C (4), xenibecin (5), xeniolide-H (6), and xenitacin (7), were isolated from the methylene chloride solubles of the Formosan soft coral Xenia umbellata. The structures were elucidated by 1D and 2D NMR spectral analysis, and their cytotoxicity against sele...

The release of organic matter (OM) by scleractinian corals represents a key physiological process that importantly contributes to coral reef ecosystem functioning, and is affected by inorganic nutrient availability. Although OM fluxes have been studied for several dominant reef taxa, no information is available for soft corals, one of the major benthic groups in tropical reef environments. Thus...

This review describes strategies for the chemical synthesis of xenicane diterpenoids and structurally related metabolites. Selected members from the four different subclasses of the Xenia diterpenoid family, the xenicins, xeniolides, xeniaphyllanes and xeniaethers, are presented. The synthetic strategies are discussed with an emphasis on the individual key reactions for the construction of the ...
