  Synthesis and evaluation of potent and selective human V1a receptor antagonists as potential ligands for PET or SPECT imaging

  摘要：

  SRX246 is a potent, highly selective human vasopressin V1a antagonist that crosses the blood-brain barrier in rats. CNS penetration makes SRX246 an ideal candidate for potential radiolabeling and use in visualization and characterization of the role of the V1a receptor in multiple stress-related disorders. Before radiolabeling studies, cold reference analogs of SRX246 were prepared. This study describes the synthesis and in vitro screening for human V1a receptor binding and permeability of fluoro, iodo, and methyl reference compounds for SRX246 and the preparation of a tin precursor. For each compound, the potential utility of corresponding radiolabeled analogs for PET and SPECT imaging is discussed. (C) 2011 Elsevier Ltd. All rights reserved.

• Metal- and Acid-Free Methyl Triflate Catalyzed Meyer–Schuster Rearrangement
  作者：Qingle Zeng、Lu Yang

  DOI：10.1055/s-0036-1588800

  日期：2017.7

  acid-free preparation of synthetically useful α,β-unsaturated carbonyl compounds from propargyl alcohols has been realized. This Meyer–Schuster rearrangement process is effectively catalyzed by methyl triflate (20 mol%) to prepare a broad scope of conjugated E-enals and E-enones generally in good to excellent yields (up to 90%). This reaction procedure operates under mild conditions (70 °C), in air

  摘要 已经实现了从炔丙醇中无金属和无酸地合成有用的α，β-不饱和羰基化合物的新方法。这种Meyer-Schuster重排过程可通过三氟甲磺酸甲酯（20摩尔％）有效催化，制备出大范围的共轭E-烯醛和E-烯酮，收率通常高达90％。该反应过程在温和条件下（70°C）在空气中进行，反应时间短（1 h）。此外，在该转化过程中分离出了被溶剂2,2,2-三氟乙醇捕获的碳正离子中间体。 已经实现了从炔丙醇中无金属和无酸地合成有用的α，β-不饱和羰基化合物的新方法。这种Meyer-Schuster重排过程可通过三氟甲磺酸甲酯（20摩尔％）有效催化，制备出大范围的共轭E-烯醛和E-烯酮，收率通常高达90％。该反应过程在温和条件下（70°C）在空气中进行，反应时间短（1 h）。此外，在该转化过程中分离出了被溶剂2,2,2-三氟乙醇捕获的碳正离子中间体。
