  通过吡啶N-氧化物制备的2-吡啶基三烷基铵盐制备2-氟吡啶的简便方法及其在18 F标签上的应用

  摘要：

  在2- [ 18 F]氟吡啶的已知前体中，吡啶基三烷基铵盐已显示出优异的反应性。然而，它们的广泛用途受到限制，因为用于其制备的合成方法具有差的官能团相容性。在本文中，我们证明了在温和且无金属的条件下，易于获得的吡啶N-氧化物向2-吡啶基三烷基铵盐的区域选择性转化。这些可分离的中间体可作为结构多样的2-氟吡啶（包括与PET成像有关的分子）的有效前体。除了提供访问非放射性类似物，此方法已被成功地应用到18 F-标记中的放射合成[ 18 F] AV-1451（[18 F] T807），目前正在开发用于对tau成像的PET示踪剂。

  We describe the hit-to-lead exploration of a [1,2,4]triazolo[1,5-a]pyrimidine phosphodiesterase 2A (PDE2A) inhibitor arising from high-throughput screening. X-ray crystallography enabled structure-guided design, leading to the identification of preferred substructural components. Further rounds of optimization used relative binding free-energy calculations to prioritize different substituents from

  Stable and efficient organic light-emitting diodes were prepared using tetradentate platinum-based blue and red emitters. In one example, a series of stable and efficient red phosphorescent OLEDs was fabricated employing a phenyl-pyridyl-carbazole based tetradentate cyclometalated Pt(II) complex as an emitting dopant and utilizing a commercially available host, transporting, and blocking materials. By implementing this platinum complex in electrochemically stable device architectures, long operational lifetimes were achieved with an estimated LT97 of over 600 hrs at luminance of 1000 cd/m2.

  使用四齿配位的铂基蓝色和红色发光材料，我们成功制备了稳定高效的有机发光二极管。例如，一系列稳定高效的红光磷光OLED就是采用基于苯基-吡啶基-咔唑的四齿配位的环金属铂(II)配合物作为发光掺杂剂，并使用商业上可获得的宿主、传输和阻挡材料来制造的。通过在电化学稳定的器件结构中实施这种铂配合物，实现了长的操作寿命，估计在亮度为1000 cd/m2时的LT97寿命超过600小时。
