  摘要：

  我们提出了一系列新颖的放射性碘示踪剂和潜在的疾病治疗学，伴随着胆碱转运蛋白的病理功能。与临床上当前使用的标有11 C或18 F的胆碱类似物不同，本文所述的碘化化合物可根据碘同位素选择，应用于正电子发射断层扫描，单光子发射计算机断层扫描以及潜在地用于治疗。而且，碘同位素的有利半衰期导致通过同位素交换反应的具有挑战性的合成要少得多。所描述的化合物中有六个是纳摩尔配体，最佳化合物的亲和力比胆碱高100倍。125的生物分布数据用I标记的人类前列腺癌（PC-3）小鼠配体显示了两种化合物，其生物分布特征优于[ 18 F]氟胆碱。

  Disclosed herein is a photochemical Heck-type arylation of vinylphenols with non-activated aryl and heteroaryl halides under visible light irradiation. Preliminary mechanistic studies suggested that the colored vinylphenolate anions acted as a strong reducing photoactivator to directly activate (hetero)aryl halides without the need for any sacrificial reductants. The photochemically generated aryl radicals

  versatile building blocks for the radiolabeling of biomolecules via Huisgen cycloaddition (“click chemistry”) for positron emission tomography (PET). However, routine access to such clickable agents is challenged by inefficient and/or poorly defined multistep radiochemical approaches. A high‐yielding direct radiofluorination for azido 18F‐arenes was achieved through the development of an ortho‐oxygen‐stabilized
