3-Fluoro-α-fluoromethyl-p-tyrosine was synthesized directly by the reaction of acetyl hypofluorite with α-fluoromethyl- p-tyrosine. α-Fluoromethyl-p-tyrosine was prepared by a four-step reaction while acetyl hypofluorite was prepared from elemental fluorine. Products were characterized by mass spectrometry, multinuclear (1H, 13C and 19F) NMR spectroscopy and HPLC. 3-[18F]-Fluoro-α-fluoromethyl-p-tyrosine
3-氟-α-氟甲基-对-酪氨酸是通过乙酰基次萤石与α-氟甲基-对-酪氨酸反应直接合成的。α-氟甲基-对酪氨酸通过四步反应制备,而乙酰基次萤石则由元素氟制备。通过质谱,多核(1 H,13 C和19 F)NMR光谱和HPLC对产物进行表征。随后由回旋加速器生产的[ 18 F]乙酰基次萤石制备3- [ 18 F]-氟-α-氟甲基-p-酪氨酸,一种多巴胺神经元的潜在显像剂,其平均放射化学产率为19.3±1.7%。
