    名称:
    Titania-Catalyzed Radiofluorination of Tosylated Precursors in Highly Aqueous Medium
    摘要:
    Nucleophilic radiofluorination is an efficient synthetic route to many positron-emission tomography (PET) probes, but removal of water to activate the cyclotron-produced [F-18]fluoride has to be performed prior to reaction, which significantly increases overall radiolabeling time and causes radioactivity loss. In this report, we demonstrate the possibility of F-18-radiofluorination in highly aqueous medium. The method utilizes titania nanoparticles, 1:1 (v/v) acetonitrile-thexyl alcohol solvent mixture, and tetra-n-butylammonium bicarbonate as a phase-transfer agent. Efficient radiolabeling is directly performed with aqueous [F-18]fluoride without the need for a drying/azeotroping step to significantly reduce radiosynthesis time. High radiochemical purity of the target compound is also achieved. The substrate scope of the synthetic strategy is demonstrated with a range of aromatic, aliphatic, and cydoaliphatic tosylated precursors.

  • Catalyst-Free Aromatic Radiofluorination via Oxidized Iodoarene Precursors

    Oxidized iodoarenes (OIAs), prepared via mCPBA-mediated oxidation, have been demonstrated as versatile precursors for the synthesis of [18F]fluoroarenes in the absence of catalysts. OIAs have been identified as intermediates in single-pot syntheses of iodonium salts and ylides but have never been recognized as radiofluorination precursors. Here, the isolated OIAs were used without any catalysts to
    氧化iodoarenes(OIAs),通过制备米CPBA介导的氧化,已经被证明是通用于[合成前体18 F]在不存在催化剂的fluoroarenes。OIAs已被确定为盐和化物单罐合成的中间体,但从未被认为是放射性化的前体。在这里,分离的OIAs无需任何催化剂即可用于生产官能化的[ 18 F]芳烃,而与芳烃的电子性质无关。该方法还用于放射性标记合成子的生产,用作芳族18 F标记的构建基块。

    radioactivities, necessitating their radiosyntheses from cyclotron-produced no-carrier-added [18F]fluoride ion. PET radiotracers encompass wide structural diversity and molecular weight. Hence, diverse 18F-labeling methodology is needed to accomplish the required radiosyntheses in a simple and rapid manner. A useful strategy is to introduce nucleophilic [18F]fluoride ion first into a labeling synthon that
    正电子发射断层扫描 (PET) 生物医学成像中迫切需要使用短寿命 18(t 1/2 = 109.7 分钟)标记的放射性示踪剂。放射性示踪剂大多需要高比放射性,因此需要从回旋加速器产生的未添加载体的[ 18 F]离子进行放射合成。PET 放射性示踪剂具有广泛的结构多样性和分子量。因此,需要多种18 F 标记方法来以简单且快速的方式完成所需的放射合成。一种有用的策略是首先将亲核[ 18 F]离子引入标记合成子中,然后将其用于标记目标放射性示踪剂。在这里,我们表明,通过适当的二芳基盐与[ 18 F]离子的一步反应,可以快速合成各种官能化的[ 18 F]芳烃作为标记合成子。衰变校正放射化学产率(RCY)随官能团的位置、二芳基鎓盐中富电子芳环的选择以及阴离子的选择而变化。在最佳条件下,以 40-73%、20-55%、46-89% 和 81-98% RCY 的选择性获得 18 F 标记的
