hydrochloride salt gave either stable isotope labeled (−)-OSU-6162 or carbon-14 labeled (−)-OSU-6162. The overall radiochemical yield was 36% with chemical and radiochemical purity exceeding 99% by HPLC analysis. The precursor thiol (5) was provided by a modified synthetic route from commercially available (S)-(−)-3-(3-(hydroxyphenyl)-1-propylpiperidine); ((S)-(−)-PPP), 2, in three steps via the tri
(-)OSU-6162,((S)-(-)-3-[3-(甲基磺酰基)苯基]-1-丙基哌啶盐酸盐),1,它是多巴胺自身受体拮抗剂,具有潜在的非典型抗精神病特性。稳定标记和碳 14 标记的 (-)-OSU-6162 的合成是通过 (S)-3-(1-丙基哌啶-3-基)-苯硫醇 5 的阴离子烷基化实现的,其中 [13C ,2H3]甲基碘或[14C]甲基碘以提供相应的甲基硫醚。甲基硫醚选择性氧化为砜并转化为其盐酸盐,得到稳定同位素标记的 (-)-OSU-6162 或碳 14 标记的 (-)-OSU-6162。通过HPLC分析,总放射化学产率为36%,化学和放射化学纯度超过99%。前体硫醇(5)由市售的(S)-(-)-3-(3-(羟基苯基)-1-丙基哌啶)通过改进的合成路线提供;((S)-(-)-PPP),2,通过三异丙基硅烷硫醇盐中间体 (7) 分三步进行。版权所有 © 2000 John Wiley
