  Flexible N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine analog: synthesis and monoamine oxidase catalyzed bioactivation

  摘要：

  Eighteen analogues of N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) were synthesized and evaluated as substrates of monoamine oxidase. In general, the flexible analogues, characterized by the presence of a methylene (or ethylene) bridge between the aryl/heteroaryl and tetrahydropyridyl moieties, were better substrates of the enzyme than the conformationally restricted MPTP. It is suggested that the increased oxidative activity of these flexible analogues reflects enhanced binding due to the ability of the C-4-aryl/heteroaryl substituent to gain access to a hydrophobic pocket within the substrate binding site.

  Pyridylmagnesiates: generation by bromine–metal exchange and enantioselective addition to aldehydes

  摘要：

  Butyl and dibutylmagnesiates incorporating chiral ligands have been prepared and their reactivity studied. The reagents were efficient to promote the clean bromine-magnesium exchange of azinyl bromides at room temperature and subsequent reaction with aldehydes affording pyridylcarbinols. (R,R)-TADDOL-based dibutylmagnesiate was the best reagent leading to acceptable to good enantioselectivities, depending on the substrate and on the aldehyde substitution. This is the first example of enantioselective addition of in situ generated pyridylmagnesiate to carbonyl electrophiles. (C) 2012 Elsevier Ltd. All rights reserved.

  interrupted carbonyl-Heck type mechanism is proposed to be operative, with a key 1,2-insertion step forging the new C–C bond and forming a nickel alkoxide that may be turned over by an alcohol reductant. The same catalyst was also found to enable synthesis of ketone products from either aldehydes or alcohols, demonstrating control over the oxidation state of both the starting materials and products.

  我们报告了一种通过芳基碘化物偶联获得仲醇的催化方法。醛或醇都可以用作反应伙伴，分别使转化还原或氧化还原中性。该反应由 Ni 催化剂和 1,5-二氮杂-3,7-二磷酸环辛烷介导。这个 P 2 N 2以前在交叉偶联和相关反应中未被识别的配体被发现可以避免有害的芳基卤化物还原途径，而这些途径主要由更传统的膦和 NHCs 支配。提出了一种间断的羰基-Heck 型机制，其中一个关键的 1,2-插入步骤形成新的 C-C 键并形成可能被醇还原剂翻转的镍醇盐。还发现相同的催化剂能够从醛或醇合成酮产物，证明对起始材料和产物的氧化态的控制。

  An efficient C–C bond formation strategy between aromatic/heteroaromatic π-nucleophiles and Lewis acid activated aldehydes is described. This aromatic electrophilic substitution reaction of arenes or heteroarenes is facilitated by Lewis acid AlBr3. Aromatic rings with electron donating substituents are excellent nucleophilic counterparts in this reaction, generating carbinols in excellent yields (61–94%)

  描述了芳族/杂芳族π-亲核试剂与路易斯酸活化醛之间有效的CC键形成策略。路易斯酸AlBr 3促进了芳烃或杂芳烃的芳族亲电取代反应。具有给电子取代基的芳香环在该反应中是极好的亲核对应物，可产生高收率的甲醇（61-94％）。在某些反应性醛和芳香族π-亲核试剂通过反应性碳正离子形成的情况下，也见证了三芳基甲烷的形成。三芳基甲烷的生成可通过以下方式更大程度地减少通过路易斯碱（例如吡啶）与烷氧基铝中间体配位的第二个π-亲核试剂加成的阻滞作用。在存在AlBr 3的情况下，各种脂肪醛也经历了Friedel-Crafts型羟烷基化反应，并以中等收率（41-53％）生成了预期的甲醇。该方案已成功地以单锅法成功用于治疗上重要的组胺H 1拮抗剂（±）-carbinoxamine的合成。

  cross-coupling strategy that enables the direct arylation of carbonyl/iminyl derivatives in the presence of Et3N has been realized. Such an atom-economical protocol furnishes a broad scope of arylation products such as secondary/tertiary alcohols and amines via a PCET process that facilitates the challenging reduction of C═X (X = O, N). Mechanistic investigation indicates two photocatalytic redox cycles

  已经实现了第一个可见光介导的自由基-自由基交叉偶联策略，该策略能够在Et 3 N存在的情况下使羰基/亚胺基衍生物直接芳基化。这种原子经济的方案通过PCET工艺提供了广泛的芳基化产物，例如仲/叔醇和胺，这有助于降低C═X（X = O，N）的挑战性。机理研究表明，该过程涉及两个光催化氧化还原循环，并且证明了Et 3 N可作为双重还原剂和质子供体。而且，分离出的副产物和受控实验可以被认为是我们的假设的有力支持证据。
