  摘要：

  将各种有机金属试剂添加到喹啉中，仅发生在杂环芳香环的2位。由此得到的2-取代的1,2-二氢喹啉随后可在乙醇中用钠轻松还原为1,2,3,4-四氢喹啉。喹啉转化为2-取代的1,2,3,4-四氢喹啉的总体过程，相较于之前文献条件（需要中间的氧化步骤），被发现更为有利。最后一步的产率范围为42-98%，但通常大于80%。

  Asymmetric hydrogenation of quinolines catalyzed by chiral cationic η(6)-arene-N-tosylethylenediamine-Ru(II) complexes have been investigated. A wide range of quinoline derivatives, including 2-alkylquinolines, 2-arylquinolines, and 2-functionalized and 2,3-disubstituted quinoline derivatives, were efficiently hydrogenated to give 1,2,3,4-tetrahydroquinolines with up to >99% ee and full conversions

  已经研究了由手性阳离子 η(6)-芳烃-N-甲苯磺酰乙二胺-Ru(II) 配合物催化的喹啉的不对称氢化。广泛的喹啉衍生物，包括 2-烷基喹啉、2-芳基喹啉和 2-官能化和 2,3-二取代的喹啉衍生物，被有效氢化得到 1,2,3,4-四氢喹啉，ee 高达 >99%和完全转换。该催化方案适用于一些具有生物活性的四氢喹啉的克级合成，如 (-)-angustureine 和 6-fluoro-2-methyl-1,2,3,4-tetrahydroquinoline，这是制备的关键中间体抗菌剂（S）-氟甲喹。该反应的催化途径已使用化学计量反应、中间体表征、和同位素标记模式。从这些实验中获得的证据表明，喹啉通过离子和级联反应途径被还原，包括 1,4-氢化物加成、异构化和 1,2-氢化物加成，并且氢加成经历了逐步的 H(+)/H( -) 协调范围之外的转移过程而不是协调机制。此外，DFT 计算表明，对映选择性源自

  A Ni-catalyzed asymmetric hydrocyanation that enables the formation of 4-cyanotetrahydroquinolines in good yields with excellent enantioselectivities is presented herein. A variety of functional groups are well-tolerated, and a gram-scale reaction supports the synthetic potential of the transformation. Additionally, several crucial intermediates for pharmaceutically active agents, including a PGD2

  Herein, we present a mild and efficient method for synthesizing enantioenriched tetrahydroquinoline-fused cyclobutenes through a cascade reaction between 1,2-dihydroquinolines and alkynones with catalysis by chiral spiro-bicyclic bisboranes. The bisboranes served two functions: first they catalyzed a hydride transfer to convert the 1,2-dihydroquinoline substrate to a 1,4-dihydroquinoline, and then

  在此，我们提出了一种温和有效的方法，通过 1,2-二氢喹啉和炔酮之间的级联反应在手性螺双环双硼烷的催化下合成对映体富集的四氢喹啉稠合环丁烯。双硼烷有两个功能：首先它们催化氢化物转移将 1,2-二氢喹啉底物转化为 1,4-二氢喹啉，然后它们激活炔酮底物与 1 进行对映选择性 [2+2] 环加成反应， 4-二氢喹啉原位生成。

  A domino reaction comprising four consecutive steps based on the strategy of isomerization of allylic alcohols was developed. This base‐catalyzed protocol provided an approach for constructing polysubstituted quinolines without additional additives. A wide range of di‐ or trisubstituted γ‐aminoaryl allylic alcohols bearing alkyl or (hetero)aryl substituents were transformed to the structurally diverse

  基于烯丙醇异构化策略，开发了包含四个连续步骤的多米诺骨牌反应。这种碱催化方案提供了一种无需额外添加剂即可构建多取代喹啉的方法。多种带有烷基或（杂）芳基取代基的二或三取代的γ-氨基芳基烯丙醇被转化为结构多样的喹啉。通过在几种多取代喹啉衍生物（包括天然产物和药物制剂）的简明合成中的应用，证明了这种转化的实用性。初步机理实验表明，γ-氨基芳基烯丙醇的异构化经历了分子内1,3-氢转移，二氢喹啉中间体的芳构化经历了两种可能的途径同时存在，即无受体脱氢和转移氢化过程。

  A series of pyrrolo[3,2,1-ij]quinoline derivatives was synthesized and evaluated for their in vitro and in vivo activities against histamine, platelet activating factor (PAF), and leukotrienes which are recognized to be of importance in asthma. The structure-activity relationship studies have shown that the optimum moiety on the 1-position of the pyrroloquinoline nucleus is a 2-[4-(4-methyl-2-pyridinyl)-1-piperazinyl]ethyl chain in conjunction with a methyl group on the 2-position for potent antagonism of both histamine and PAF. The introduction of substituents on the 8- and 4-positions was also investigated in order to increase the potency of 5-lipoxygenase inhibition while retaining or improving the activities against histamine and PAF. This series is exemplified by 4-n-butyl-5,6-dihydro-8-hydroxy-2-methyl-1-[2-[4-(4-methyl- 2-pyridinyl)-1-piperazinyl]ethyl]-4H-pyrrolo[3,2,1-ij]quinoline (24, KC 11404) which was found to be active against all three of the selected mediators. Compound 24 was found to be orally active in guinea pig models against the histaminic phase of antigen-induced bronchospasm and PAF-induced bronchoconstriction (ED(50) = 1.9 and 2.1 mu mol/kg, respectively). When tested against the leukotriene-dependent phase of the antigen-induced bronchoconstriction, compound 24 showed the same potency as zileuton.
