Hypoxia is related with many tumors due to a decreased oxygen condition. Novel synthesis for 1‐(2‐nitro‐1H‐imidazol‐1‐yl)‐3‐(tosyloxy)propan‐2‐yl acetate for the radiosynthesis of the [
18F]‐Flouromisonidazole ([
18F]‐FMISO), a hypoxia imaging marker used in positron emission tomography, from the readily available starting material is described. In this approach, one‐pot two‐step syntheses were used for the preparation of the [
18F]‐FMISO precursors that contain acetyl group. The mild reaction conditions and easy treatments are attractive features in this synthesis. This new synthetic route provides alternative choices for the preparation of hypoxia imaging marker.
缺氧与许多肿瘤有关,因为氧气含量降低。1-(2-硝基-1H-咪唑-1-基)-3-(对甲苯磺酰氧基)丙-2-基乙酸酯的新合成方法,用于[18F]-氟苯并咪唑([[18F]-Flouromisonidazole)的放射合成。
18F]-Flouromisonidazole ([
18F]-FMISO),这是一种用于正电子发射断层扫描的缺氧成像标记物。该方法采用一锅两步合成法制备了[18F]-FMISO。
18F]-FMISO 前体。这种合成方法的特点是反应条件温和、处理简单。这种新的合成路线为制备缺氧成像标记物提供了另一种选择。
