The first direct C-H F fluorination reaction of unactivated aliphatic sites using no-carrier-added [F]fluoride is reported. Under the influence of a manganese porphyrin/iodosylbenzene system, a variety of unactivated aliphatic C-H bonds can be selectively converted to C-F bonds. The mild conditions, broad substrate scope and generally inaccessible regiochemistry make this radio-fluorination a powerful alternate to established nucleophilic substitution for the preparation of F labeled radio tracers.
报道了使用无载体添加的[F]氟化物对未活化脂肪族位点进行的首例直接C-H氟氟化反应。在锰卟啉/碘苯体系的影响下,多种未活化的脂肪族C-H键可选择性地转化为C-F键。温和的条件、广泛的底物范围以及一般难以实现的区域化学性质,使得这种放射性氟化成为制备F标记放射性示踪剂时,替代既定亲核取代反应的一种强大方法。
