The tetracyclic ketone 17, which possesses a framework closely related to phorbol, has been prepared in enantiomerically pure condition. Condensation of the dichlorocerate derived from 3 with 2-chlorocyclohexanone leads to chlorohydrins 4 and 5 in a 1:1 ratio. Treatment of 5 with excess vinylmagnesium bromide delivers 7, thereby setting the stage for anionic oxy-Cope rearrangement to 9. Epoxidation
