  在犬第二代幼虫中与哌酰胺有关的芳烷基和芳烯基酰胺的合成和杀线活性。

  摘要：

  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。

  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.

• Concise, efficient new synthesis of pipercide, an insecticidal unsaturated amide from Piper nigrum, and related compounds

  日期：1994.1

  Pipercide and piperolein A, unsaturated amides from Piper nigrum, were prepared in overall yields of 21% and 35% respectively, by a new, short and efficient strategy, in which the key step was the aldol-Grob-type fragmentation sequence recently reported by Sakai et al.. (but using propylene- rather than ethylene glycol). The nor-homologues of these natural products were similarly prepared. In the final

  通过新的，短而有效的策略，分别从Piper nigrum制备了总产率分别为21％和35％的Pipercide和Piperolein A（不饱和酰胺），其中的关键步骤是最近报道的aldol-Grob型片段化序列。 Sakai等人（但使用丙二醇而不是乙二醇）。这些天然产物的非同源物以类似方式制备。在最后的步骤中，可以通过Roskamp的方法（包括用Sn [N（TMS）2 ] 2和适当的胺处理）直接从酯中制备酰胺，或者通过常规方法从相应的羧酸中制备酰胺。
