摘要: 以易得的环十二酮为原料,由磺化获得中间体α-氧代环十二烷基磺酸后,再经生成磺酰、氯和胺化反应合成了一系列N-取代-α-氧代环十二烷基磺酰胺(Ⅲ).生物活性测定结果表明,它们对小麦赤霉病菌(Gibberellazeae)的生长具有抑制作用,其中活性最高的是氮上取代有一氯苯基的化合物(Ⅲ7、Ⅲ8),通过构象分析讨论了它们的结构-活性关系.

Abstract: Aseries of N-substituted-a-oxocyclododecylsulphonamides (Ⅲ) have been synthe-sized by amination of a-oxocyclododecylsulphonic acid chloride, obtained from the readily available cyclododecanone via a-oxocyclododecylsulphonic acid. Their structures were con-firmed by IR, MS, 1H NMRand elementary analysis. The bioassay for antifungal activitywas carried out and all the title compounds were found to be active against Gibberella zeae.The compounds showing the highest activity are those substituted by a chlorophenyl group on the nitrogen atom (Ⅲ 8, Ⅲ 7). Their structure-activity relationship was discussed by means of conformational analysis.
