of six EKODE regio- and stereoisomers, two trans α‘,β‘-epoxy-α,β-enones, and two trans and the two cis γ,δ,-epoxy-α,β-enones was accomplished, with the key steps being Wittig-type reactions and aldol condensations. All six EKODE isomers were confirmed by HPLC to be generated in the autoxidation of linoleic acid promoted by Fe(II)/ascorbic acid through spiking in of authentic samples. On the basis of
