A large series of analogues of Eunicea cembranolides 1–3 were synthesized with the purpose of evaluating their cytotoxicity against 60 human cancer cell-lines. Most of the analogues were as active as the lead compounds and a few displayed increased cytotoxicity. Their syntheses were based on the specific reactivity and stereochemistry of the epoxide substructure and involved highly regio- and diastereoselective

γ-lactonic cembranolides were isolated from the gorgonianEunicea succinea collected near Palomino Key, Puerto Rico on July,1989. The structure of two were determined from spectral data and chemical correlation experiments to be those of known 12,13-bisepleupalmerin (1) and eunicin (3). The structure of the third metabolite was deduced from spectroscopic data and from chemical degradation experiments to
