8-alkadienyl esters upon reaction with triphenylphosphinecopper hydride hexamer stereoselectively yields substitutedcyclohexanones having a cis relationship of carbon side chains at C2 and C3. This cyclohexanone construction is particularly useful for preparing 4-alkoxy- or 4-siloxy-2,3-disubstituted cyclohexanones, in which instance stereoselection is > or = 20:1.
