  Hindered rotation congeners of mazapertine: High affinity ligands for the 5-HT1A receptor

  摘要：

  Hindered rotation analogs of the antipsychotic mazapertine (1) were prepared. These compounds exhibited high affinity for the 5-HT1A receptor, but not for other serotonin or dopamine receptors. The related beta-carboline structures were also synthesized and were found to be potent 5-HT1A ligands. (C) 1997 Elsevier Science Ltd.

  Antihypertensive indole derivatives of phenoxypropanolamines with .beta.-adrenergic receptor antagonist and vasodilating activity

  摘要：

  A series of 25 aryloxypropanolamines containing the 3-indolyl-tert-butyl [i.e., 1,1-dimethyl-2-(1H-indol-3-yl)ethyl] or substituted 3-indolyl-tert-butyl moiety as the N substituent is reported. These compounds have been tested for antihypertensive activity in spontaneously hypertensive rats (SHR), beta-adrenergic receptor antagonist action in conscious normotensive rats, vasodilating activity in ganglion-blocked rats with blood pressure maintained by angiotensin II infusion, and for intrinsic sympathomimetic action (ISA) in reserpinized rats. Some of the compounds exhibit antihypertensive activity in combination with beta adrenergic receptor antagonist and vasodilating action. The structure--activity relationships in these tests are discussed.

  ortho‐substituted phenyl glycidyl ethers and para‐nitrostyrene oxide. Worthy of note is that the substrate structure remarkably affected the enantioselectivities of the enzyme, as a reversed (S)‐enantiopreference was unexpectedly observed for the ortho‐nitrophenyl glycidyl ether. As a proof‐of‐concept, five enantiopure epoxides (>99% ee) were obtained in high yields, and a gram‐scale preparation of

• A concise and simple click reaction catalyzed by immobilized Cu(I) in an ionic liquid leading to the synthesis of β-hydroxy triazoles
  作者：Nasseb Singh

  Résumé This study describes an ecocompatible, concise, and practically reliable approach for the regioselective synthesis of β-hydroxy triazoles via Huisgen's click coupling reaction among varied epoxides, NaN3, and suitable acetylenes catalysed by immobilized Cu(I) in ionic liquid (IL). This one-pot, atom-economic, efficient, and highly regioselective green protocol ensures higher yield of β-hydroxy triazole scaffolds (85–95%). To make the process ecofriendly, this study emphasizes on the catalyst immobilization technique along with its possible recycling that gave a high reaction yield in up to three runs. The structures of all synthesized compounds have been characterized by comparing 1H nuclear magnetic resonance (NMR), 13C NMR, and mass spectroscopic data with those reported in the literature.

  摘要 本研究描述了一种环保、简便且实用的方法，通过固定在离子液体（IL）中的Cu(I)催化的不同环氧化物、NaN3和合适炔烃之间的Huisgen点击偶联反应，选择性地合成β-羟基三氮唑。这种一步法、原子经济性高、效率高且具有高度区域选择性的绿色协议确保了β-羟基三氮唑骨架的高产率（85-95%）。为了使该过程更加环保，本研究强调了催化剂固定化技术及其可能的回收利用，使得反应在最多三批次运行中仍能保持高产率。所有合成化合物的结构已通过与文献报道的1H核磁共振（NMR）、13C NMR和质谱数据进行比较来表征。
