  The synthesis of novel GABA uptake inhibitors. 1. Elucidation of the structure-activity studies leading to the choice of (R)-1-[4,4-bis(3-methyl-2-thienyl)-3-butenyl]-3-piperidinecarboxylic acid (Tiagabine) as an anticonvulsant drug candidate

  摘要：

  A series of different synthetic approaches to novel GABA uptake inhibitors are described, leading to examples which are derivatives of nipecotic acid and guvacine, substituted at nitrogen by 4,4-diaryl-3-butenyl or 2-(diphenylmethoxy)ethyl moieties. The in vitro value for inhibition of [H-3]-GABA uptake in rat synaptosomes was determined for each compound. It was found that the most potent examples are those having a substituent in an ''ortho'' position in one or both aromatic/heteroaromatic groups. The majority of the compounds described are structurally related to tiagabine, (R)-1-[4,4-bis(3-methyl-2-thienyl)-3-butenyl]-3-piperidinecarboxylic acid hydrochloride (NNC 05-0328) and some of the reasoning behind the selection of this compound as a drug candidate is summarized.

• Palladium-Catalyzed Carbonylative Cross-Coupling Reaction between Aryl(Heteroaryl) Iodides and Tricyclopropylbismuth: Expedient Access to Aryl Cyclopropylketones
  作者：Emeline Benoit、Julien Dansereau、Alexandre Gagnon

  DOI：10.1055/s-0036-1590832

  日期：2017.12

  The carbonylative cross-coupling reaction between aryl and heteroaryl iodides and tricyclopropylbismuth is reported. The reaction is catalyzed by (SIPr)Pd(allyl)Cl, a NHC-palladium(II) catalyst, operates under 1 atm of carbon monoxide and tolerates a wide range of functional groups. The use of lithium chloride was found to provide higher yields of the desired aryl cyclopropylketones. The conditions

  报道了芳基和杂芳基碘化物与三环丙基铋之间的羰基化交叉偶联反应。该反应由 (SIPr)Pd(烯丙基)Cl 催化，这是一种 NHC-钯 (II) 催化剂，在 1 个大气压的一氧化碳下运行，并能耐受多种官能团。发现使用氯化锂可提供更高产率的所需芳基环丙基酮。该条件也适用于碘代烯烃的羰基化交叉偶联，以提供相应的烯基环丙基酮。

  An iodine‐mediated oxidative ring contraction of cyclobutanols has been developed. The reaction allows the synthesis of a wide range of aryl cyclopropyl ketones under mild and eco‐friendly conditions. A variety of functional groups including aromatic or alkyl halides, ethers, esters, ketones, alkenes, and even aldehydes are nicely tolerated in the reaction. This is in contrast with traditional synthetic

  已经开发出碘介导的环丁醇的氧化环收缩。该反应可以在温和且环保的条件下合成各种芳基环丙基酮。反应中可以很好地耐受各种官能团，包括芳族或烷基卤化物，醚，酯，酮，烯烃，甚至醛。这与传统的合成方法相反，在传统的合成方法中，官能团的耐受性通常很差。碘氧化系统的可调性也突出了该方法的实用性。具体而言，将碘（III）试剂与适当的碱结合使用可使反应适应一系列富挑战性的富电子芳烃底物。在此也显示了该反应的简便可扩展性。

• Synthesis and photosensitized oxygenation of cyclopropylidenecyclobutenes

  Cyclopropylidenecyclobutenes and -cyclobutanes were conveniently prepared using the Petasis titanocene approach. The cyclobutenes were unreactive to singlet oxygen, reacting sluggishly via a photoinitiated free radical autooxidative epoxidation process, to yield the corresponding spiroketones. By contrast, cyclopropylidenecyclobutanes react rapidly with 1O2, via an ‘ene’ process, initially generating

  使用Petasis二茂钛方法可方便地制备环丙叉基环丁烯和-环丁烷。环丁烯与单线态氧不反应，通过光引发的自由基自氧化环氧化过程缓慢反应，生成相应的螺酮。相比之下，环亚丙​​基环丁烷通过“烯”过程与1 O 2迅速反应，最初生成环丙基氢过氧化物，然后通过Hock裂解反应生成产物。环亚丙基环丁烯对1 O 2 '烯'反应模式的惰性可归因于以下事实：它需要形成相对较高能量的环丁二烯部分。

  reported. For the majority of VCPs, little or no ring opening of the cyclopropyl unit is observed. Conversely, for VCPs with bulky R groups, such as ortho-substituted aryl rings or branched alkyl residues, ring opening is the exclusive reaction pathway. This finding is explained by the thwarted hydride delivery to a sterically shielded, β-silicon-stabilized cyclopropylcarbinyl cation intermediate.

  据报道，强硼路易斯酸B（C 6 F 5）3催化乙烯基环丙烷（VCP）的硅氢化。对于大多数VCP，观察到很少或没有环丙基单元的开环。相反，对于具有庞大R基团的VCP，例如邻位取代的芳基环或支链烷基残基，开环是唯一的反应途径。这一发现可以通过阻止氢化物向空间屏蔽的，β-硅稳定的环丙基羰基阳离子中间物的传递来解释。
