Seven homoserine-lactone (HL) acylated derivatives (HL1-HL7) were synthesized to determine the differences in antifeedant affects. The differences between these derivatives and tutin against Mythimna separata were tested. The structural assignments of these semisynthetic compounds were examined based on their infrared radiaion (IR), electrospray ionization mass spectrometry (ESIMS), and ¹H- and ¹³C-nuclear magnetic resonance (¹³C-NMR) spectral data. Compound HL1 (N-(4-nitrobenzoyl)-homoserinelactone) is the optimized insecticidal agent among these compounds. In addition, the antifeedant activities between homoserinelactone and 7-hydroxycoumarin, tutin derivatives with the same acidylated substitutions were compared, which could help design and synthesize stronger novel botanical insecticides.
合成了 7 种高丝氨酸内酯（HL）酰化衍生物（HL1-HL7），以确定其抗食作用的差异。这些衍生物与除虫菊酯对粘虫的差异进行了测试。根据它们的红外辐射（IR）、电喷雾电离质谱（ESIMS）和 1H-和 13C-核磁共振（13C-NMR）光谱数据，对这些半合成化合物的结构进行了分析。化合物 HL1（N-（4-硝基苯甲酰基）-高丝氨酸内酯）是这些化合物中优化的杀虫剂。此外，还比较了高丝氨酸内酯与具有相同酰化取代的 7-羟基香豆素、除虫菊酯衍生物之间的抗食活性，这有助于设计和合成更强的新型植物性杀虫剂。
