Abstract Epoxidation of methyl dehydro-β-ionylideneacetates with perbenzoic acid afforded methyl 1', 2'-epoxy-dehydro-β-ionylideneacetates and then methyl 1', 2'-, 3', 4'-di-epoxy-dehydro-β-ionylideneacetates. 1', 2'-Epoxy-dehydro-β-ionone, obtained byepoxidation of dehydro-β-ionone, was treated with carbethoxymethylenetriphenlphosphorane to give ethyl 1', 2'-epoxy-dehydro-β-ionylideneacetates. Further, sensitive photooxidation of ethyl dehydro-β-ionylidenecrotonate, followed by alkaline hydrolysis, gave 1'-hydroxy-4'-keto-α-ionylidenecrotonic acid. Growth inhibitory activities of the above compounds on rice seedlings were examined.
