  摘要：

  Pymetrozine (1) 通过用氧捕获其二价阴离子，然后用亚铁盐还原，以低到中等产率转化为半胺 2。Pymetrozines 18 和 19 未能进行这种类型的氧化。所有三种吡蚜酮均在 C5 处被电化学氧化为甲基半胺 20、21 和 22。20 到 2 的水解在酸或碱催化条件下以优异的产率完成，而甲基半缩醛 21 和 22 的水解最好在碱性条件下进行。pymetrozine 1、半胺类 2 和 3 的土壤代谢物以中等规模制备，产量极好。线性扫描伏安法数据和制备规模电化学条件是为前体吡蚜酮提供的。为所有新化合物提供完整的实验和光谱数据，并讨论了烷基酰胺的阴离子氧化与电化学氧化的相对优点。由于潜在的爆炸危险，对大规模阴离子氧化条件的描述提供了警告说明。
