aryl-SO2-18F from arenediazonium tosylates with a SO2 source and [18F]fluoride. This approach is compatible with a wide range of substrates and enabled the production of 18F-labeled drug-like derivatives through late-stage 18F fluorination, representing a significant advance in the radiosynthesis of 18F-labeled arenesulfonyl fluorides.

开发了一种新的18 F 标记策略,以使用 SO 2源和 [ 18 F] 氟化物从甲苯磺酸芳烃中直接构建芳基-SO 2 - 18 F。这种方法与广泛的底物兼容,并能够通过后期18 F 氟化生产 18 F-标记的药物样衍生物,代表18 F-标记的芳烃磺酰氟的放射合成取得了重大进展。反应性18 F 标记合成子,带有基于马来酰亚胺的辅基,可生成18通过马来酰亚胺-半胱氨酸化学,F 标记的含有半胱氨酸残基的温度敏感生物分子。
