Reaction of the trimethylsilyl (TMS) enol ethers 6 derived from the conjugate addition of oganocopper reagents to 3,4-dimethylcyclopentenone with dimethyl dioxirane (DMDO) leads to α-hydroxy ketones 7 with predominantly the syn-methyl orientation. Exposure of these systems to methanolic lead tetraacetate (Pb(OAc)4) delivers aldehydic esters 8 which are homologated to die desired E-dienes 9 using Yamamoto's allylic phosphine oxide reagent.
