Enantiomerically pure 1, 2‐diamino‐1‐(4‐fluorophenyl)butanes were synthesized by stereoselective procedures. The enantiomeric purity was determined by 1H NMR spectroscopy after derivatization with (1R)‐myrtenal. For the coordination to platinum, the diamines were reacted with K2PtI4. Reaction with Ag2SO4 yielded the respective sulfatoplatinum(II) complexes, which were converted into the dichloroplatinum(II)
对映异构纯 1, 2-diamino-1- (4-fluorophenyl) 丁烷是通过立体选择性程序合成的。在用(1R)-肉豆蔻醛衍生化后,通过 1H NMR 光谱测定对映体纯度。为了与铂配位,二胺与 K2PtI4 反应。与 Ag2SO4 反应产生相应的硫酸合铂 (II) 配合物,通过用 2N HCl 处理将其转化为二氯铂 (II) 配合物。在MCF-7和MDA-MB 231乳腺癌细胞系以及LnCaP/FGC前列腺癌细胞系上研究了构型和离去基团种类对抗肿瘤活性的影响。结果表明,二氯铂 (II) 复合物比各自的二碘铂 (II) 衍生物更具活性。转化为硫酸铂 (II) 复合物进一步增强了抗增殖作用。该配置决定了抗肿瘤作用,取决于所使用的细胞系:MCF-7:(R, R)> (S, S)> (R, S)> (S, R);MDA-MB 231:(S,S)>(R,R)>(R,S)=(S,R);LnC
