摘要:
A highly regioselective method was developed for ring-opening benzyloxycarbonyl (Cbz)-protected 2-methylaziridine with [F-18]-labelled fluoride. Following catalytic hydrogenation, 1-[F-18]fluoro-2-propanamine([F-18]1) and 2-[F-18]flouro-1-\propanamine([F-18]2) were prepared as the major and minor products, respectively (85:15), and were characterized following acylation with benzyl chloride, This methodology is applicable towards the generation of new [F-18]-labelled amines for incorporation into radiopharmaceuticals.
