BACKGROUND
Alpha-asarone (2,4,5-trimethoxypropenylbenzene) derivatives represent a new series of compounds that possess good antifeedant activity against different stored-product pests.
RESULTS
A total of 23 novel alpha-asarone derivatives were synthesised and identified by (1) H NMR, (13) C NMR and IR, and their feeding deterrent activities were tested against Sitophilus granarius L., Trogoderma granarium Ev. and Tribolium confusum Duv. Ten compounds showed strong antifeedant activities.
CONCLUSION
Some of the title compounds displayed very good and broad-spectrum activities against adult and larval Coleoptera. The results indicate that the presence of a double bond in the side chain and three methoxy groups is important for antifeedant activity.
背景
α-细辛脑（2,4,5-三甲氧基丙烯基苯）衍生物是一类新型化合物，对不同的仓储害虫具有良好的拒食活性。
结果
通过 1H NMR、13C NMR 和 IR 对总共 23 种新型 α-细辛脑衍生物进行了合成和鉴定，并对其拒食活性进行了测试，结果表明，这些化合物对玉米象、赤拟谷盗和杂拟谷盗的成虫和幼虫均具有较强的拒食活性。
结论
部分标题化合物对鞘翅目具有非常好和广谱的活性。结果表明，侧链中双键和三个甲氧基的存在对拒食活性很重要。
