【Abstract】 The present report deals with the synthesis of a series of pyrethroid-like oxime-ether compounds, their structure characteristic and the relation of structure-biologic activity.Compounds I ( R = h alogen, and R’ = i-propyl or cyclo-propyl ) show high insecticidal activities against Army worms ( Leucania Separata). Their toxicities ( LD50) close to that of Shumizize(S-5602)and surpass that of DDT.The acute oral toxi-city of compound I ( R = Cl, R’=i-pr) against mice indicated both E-and Z-isomers have LD50>4500mg/Kg. Similar to conventional pyrethro-ids, both isomers did not inhibit choline esterase.更多还原
