A novel route to enantioenriched (+)-goniodiol and its natural acetylated derivatives, potent cytotoxic compounds, is described. The main features of this synthesis are transfer of the asymmetric information of the scalemic allenic alcohol 5 to the α- and β- carbons through highly diastereoselective reactions and introduction of the α,β-unsaturated lactone moiety by the Ghosez' methodology.
