  新的5-取代的苯并[ b ]噻吩衍生物的合成

  摘要：

  我们小组以前的工作涉及1-（芳基）-3- [4-（芳基）哌嗪-1-基]丙烷衍生物的合成，以寻找具有双重作用方式的新型高效抗抑郁药：5-羟色胺再摄取抑制和5-HT 1A受体的亲和力[1-4]。从这些研究中我们得出结论，3- [4-（芳基）哌嗪-1-基] -1-（苯并[ b ]噻吩-3-基）丙烷衍生物导致了最佳结果。该研究项目的继续，需要制备一些新的3-酰基-5-取代的苯并[ b ]噻吩，其在5位上具有广泛的取代基，范围从硝基到羟基衍生物。为了获得这些衍生物，我们尽可能地将相应的5-取代的苯并[ b ]噻吩酰化。

  Starting from 1 (MEN14268), a selective tachykinin NK2 receptor antagonist with an interesting in vitro pharmacological profile, a family of numerous antagonists was obtained through an optimization process focused on iterated structural modifications. The effects of the introduction of a wide variety of substituents on the lipophilic aromatic part of the molecule and the modulation of the structural constraint

  从1（MEN14268）开始，这是一种具有令人感兴趣的体外药理学特性的选择性速激肽NK2受体拮抗剂，通过专注于重复结构修饰的优化过程获得了众多拮抗剂家族。研究了在分子的亲脂性芳族部分上引入各种取代基的影响以及通过插入不同的非手性α，α-二烷基氨基酸对结构约束的调节。特别地，在伪N-末端残基处引入芳族和苯并稠合的杂芳族部分以取代2-苯并噻吩部分，并且据报道对苯并噻吩核心的取代基在芳族平台上的最佳定位进行了系统研究。提出了对亲水性假C末端侧基的长度和刚性的调节的研究。在配体的这一部分中，受体对许多杂脂族基团具有很好的耐受性。由于在豚鼠静脉内，十二指肠内和口服给药后具有良好的体内活性，最终选择了在苯并噻吩上带有甲基取代基和四氢吡喃基甲基哌啶侧基的产物48f（MEN15596）。

  The reaction of aryl thiophene-2-carbodithioates or thiophene-3-carbodithioates with difluorocarbene generated from BrCF2CO2Li/molecular sieves 4A produced arylsulfanylated 2,2-difluoro-3-thienylthiiranes. In the presence of lithium ion, the thiirane intermediates underwent ring expansion followed by HF elimination, leading to fluorinated thieno[3,2-b]thiophenes or thieno[2,3-b]thiophenes. The reactions

  芳基噻吩-2-碳二硫酸酯或噻吩-3-二硫代碳酸酯与由 BrCF 2 CO 2 Li/分子筛 4A 生成的二氟卡宾反应产生芳基硫烷基化 2,2-二氟-3-噻吩基硫杂环丙烷。在锂离子存在的情况下，硫杂丙环中间体经历扩环然后消除HF，产生氟化噻吩并[3,2- b ]噻吩或噻吩并[2,3- b ]噻吩。氧类似物芳基呋喃碳二硫酸酯的反应也进行得到相应的噻吩并[3,2- b]呋喃。生成的芳基硫烷基（氟）噻吩并呋喃中的分子内氟取代允许构建另一个噻吩环，从而合成稠合的五环噻吩并呋喃。
