  Intramolecular anodic olefin coupling reactions: a useful method for carbon-carbon bond formation

  摘要：

  The utility of intramolecular anodic olefin coupling reactions for effecting carbon-carbon bond formation has been examined. All of the successful cyclizations studied utilized either an alkyl or silyl enol ether as one of the participating olefins. The enol ethers could be coupled to simple alkyl olefins, styrenes, and allylsilanes in isolated yields ranging from 57 to 84%. The reactions were found to be effective for generating both five- and six-membered rings. The best conditions for cyclization utilized a reticulated vitreous carbon anode, constant-current conditions in an undivided cell, and a lithium perchlorate in either 50% methanol/tetrahydrofuran or 20% methanol/dichloromethane electrolyte solution. The use of an allylsilane as one of the participating olefins allowed for the regiospecific formation of olefinic products. In addition to the olefinic products, these reactions produced a small amount of a cyclized ether product in which the silyl group had not been eliminated. Deuterium-labeling studies showed that at least half of this ether byproduct arose from intramolecular migration of the methoxy group that was initially part of the starting enol ether to the carbon-beta to the silyl group. Intramolecular migration reactions of this type were found to participate in a number of the reported cyclization reactions.

  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。

  conditions atom transfer products (17a–c, 18c,d) were obtained exclusively, whose regio- and stereochemistry were dependant on the olefinic acceptor. Thus, irradiation of the ester trans-16a or the phenyl derivative 16b (E/Z mixture) gives the trans-cyclopentyl derivatives 17a and 17b; the bromide 16c (R=Me) affords a mixture of the trans-cyclopentyl compound 17c and a comparable amount of the cyclohexyl

  Ceric ammonium nitrate oxidizes unsaturated ketene dithioacetals in wet MeCN to give cation radicals that cyclize to tri-substituted double bonds and styrenes by cation-like cyclizations leading to cyclic cation radicals that are transformed by further oxidation, hydrolysis and cyclization to bicyclic lactones in moderate to good yield.
