Enantioselective synthesis of (+)-goniodiol and of its naturally occurring acetylated analogs

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 diastercoselective reactions and introduction of the α,β-unsaturated lactone moiety by the Ghosez' methodology.

Total synthesis of (+)-goniodiol

Cytotoxic styryl lactone, (+)-goniodiol 1, was prepared in enantioenriched form (33 92%) in 15 steps from the α-(α'-alkoxyallenic) alcohol 5.
