Two stereospecific total syntheses of -widdrol () are reported. The first synthesis features the cyclization of dienone to construct bicyclic adduct which is converted to -widdrol using conventional procedures. A second synthesis exploits the cyclization of dienone 17 to prepare functionalized bicyclo[5.4.0]undecene , which is converted to a known -widdrol precursor.
