【摘要】 以丙酮和草酸二乙酯为原料,经Claisen缩合,Knorr法环化等一系列反应合成腈吡螨酯及其异构体,其结构经Mass和1H NMR等确证。初步生物活性测定结果表明,腈吡螨酯(E体)在低至1.0 mg/L浓度下对红蜘蛛仍表现出95.11%的优异活性,而相同条件下腈吡螨酯的异构体(Z体)对红蜘蛛的活性仅64.35%。更多还原

【Abstract】 They were synthesized by Claisen condensation, Knorr cyclization and some other reactions by using acetone and diethyl oxalate as raw materials. Their structures were confirmed by MS and1 H NMR spectra.Preliminary bioassay results showed that cyenopyrafen(E isomer) had 95.11% activity against Tetranychus Urticae at a concentration of 1 mg/L, while at the same condition, its isomer(Z isomer) only showed 64.35% activity.更多还原
