  A Practical and Efficient Synthetic Route to Dihydropipercide and Pipercide¹

  摘要：

  Dihydropipercide 1 and Pipercide 2 are examples of hydrophobic insecticidal isobutylamide derivatives isolated from Piper Nigrum L. which have received synthetic attention over the past decade. Novel structural features combining the N-isobutyldieneamide array, found in related natural products such as Pellitorine, with the 3,4-methylenedioxyphenyl moiety, found in insecticide synergists including Piperonyl Butoxide and Sesamex, render these as attractive targets for synthesis. Although a variety of synthetic routes to related natural products have appeared in the literature, practical methods for the preparation of the title compounds were lacking. Convenient and convergent 10-11-step protocols were developed which provided access to gram quantities of the targets. Methyl 6-oxohexanoate 4 was prepared from cyclohexanone enol acetate 3 via a tandem ozonolysis, methanolysis, hydrolysis process. Subsequent olefination and olefin isomerization steps followed by further elaboration provided the targets 1 and 2. Noteworthy features of this methodology include the convenient synthesis of oxoester intermediate 4 and the phenythio radical-induced olefin isomerization of intermediate 6 which afforded high yields of >99.5% E-olefin 13. These are both somewhat uncommon but potentially useful processes which may find further application in organic synthesis.

  piperamides (3,4-methylenedioxyphenyl homologues) showed the strongest activity among the homologues tested, methoxy substituent(s) on the aromatic ring did not have much effect on the activity. However, conversion of the methoxy group to a hydroxy group greatly decreased the activity and shortened the chain length giving the strongest activity. Calculated log P values of non-phenolic aryl-piperamides fell

  合成了与哌啶相关的79个芳烷基和芳烯基酰胺，并研究了它们对犬round虫Toxocara canis的第二级幼虫的杀线虫活性。活性很大程度上取决于烷基链的长度和胺部分的性质，但是几乎不受链中是否存在双键的影响。在一系列同系物中表现出最强活性的烷基链长，对于吡咯烷酰胺为m = 11，对于N-甲基哌嗪酰胺为m = 13。尽管在所测试的同系物中，哌啶（3，4-亚甲基二氧苯基同系物）显示出最强的活性，但是芳环上的甲氧基取代基对该活性没有太大影响。然而，甲氧基向羟基的转化大大降低了活性并缩短了链长，从而提供了最强的活性。计算出的非酚芳基哌啶的log P值在3.5至4.5范围内，而羟苯基哌啶的log P值较小，表明酚和非酚化合物的杀线活性涉及不同的机理。
