AbstractThe Baeyer-Villiger oxidn. of some Me, Me 2 and Me 3 substituted cyclohexanones with m-CIC 6H 4COOH afforded resp. e-lactones. Unsatd. terpenoid ketones: (-)-verbenone and (+)-dihydrocarvone were oxidized under the same conditions to mixts. of resp. epoxyketones and epoxy-e-lactones. The products were isolated by column chromatog., identified by NMR and IR spectroscopy and tested for antifeedant activity against the adults of the grain weevil, the adults and larvae of the confused flour beetle and the larvae of the khapra beetle. The epoxylactone obtained from (-)- verbenone showed the highest antifeedant activity against the adults of grain weevil (Sitophilus granaries, L).
