  合成拟除虫菊酯杀虫剂的手性稳定性。

  摘要：

  合成拟除虫菊酯是由多种立体异构体组成的手性化合物。对环境命运和生态毒性中对映选择性的评估需要在分析过程中保留立体异构体完整性的分析方法。在这项研究中，我们通过气相色谱（GC）分析和样品表征了四种常用拟除虫菊酯（顺式联苯菊酯（cis-BF），氯菊酯（PM），氯氰菊酯（CP）和氯氟氰菊酯（CF））的立体异构体的稳定性。准备。发现顺式-BF和PM的立体异构体是稳定的，而CP和CF的立体异构体在加热或水中不稳定。异构体转化仅发生在CP或CF的alphaC处，导致分析物立体异构体转化为差向异构体。在260°C的GC入口温度下，CP和CF的转化率约为9％。在有机溶剂和无菌水中，顺式-BF和PM的立体异构体是稳定的，但在室温下水中的CP和CF观察到缓慢的异构体转化。但是，当GC进样口温度保持在<或= 180℃或使用柱上进样时，CP和CF的异构体转化率相对较小（2-3％）。水中αC的异构体转化表明，非生物

  Epimerization of Cypermethrin Stereoisomers in Alcohols

  摘要：

  Isomerization induced by light, heat, and organic solvents has been shown to occur for some pyrethroid insecticides. Alcohols are popular solvents that are used in sample extraction, storage, and analysis. Thus, alcohol-induced epimerization may contribute to the incorrect interpretation of results from enantioselective chemical analysis and bioassay of pyrethroids like cypermethrin. In this study, we investigated the relationship between the rate of epimerization of cypermethrin stereoisomers: 1R-cis-alpha R and 1R-trans-alpha R and short-chain alkyl alcohol properties. In this study, complete epimerization of 1R-cis-alpha R produced an almost equal fraction of 1R-cis-alpha S, and that of 1R-trans-alpha R yielded 1R-trans-alpha R For both stereoisomers, epimerization was most rapid in ethanol. The same stereoisomers underwent relatively rapid epimerization in methanol, n-propanol, 2-methyl-1-propanol, and n-butanol but were stable in 2-butanol, suggesting that secondary alcohols have reduced reactivity, likely due to steric hindrance. We further evaluated epimerization of 1R-cis-alpha R and 1R-trans-alpha R stereoisomers of cypermethrin as a function of water content in methanol. The presence of water in methanol generally increased the epimerization rate. For 1R-cis-alpha R, epimerization was most rapid with a water content of <= 2%, while for 1R-trans-alpha R, epimerization was most rapid with a water content of 10%. Results from this study clearly show that contact with commonly used primary alcohols may result in rapid abiotic epimerization, underscoring the importance of considering configurational stability in ensuring the analytical integrity and correct interpretation of bioassay data for stereoisomers of cypermethrin and similar pyrethroids.
