The synthesis of the bis‐acrylate 12, the bis‐β‐chloropropionate 13 and the bis‐β‐bromopropionate 14 of the “partial” antiestrogen 2,3‐bis(2‐fluoro‐4‐hydroxyphenyl)‐2,3‐dimethylbutane (7) is described. In the case of 13 and 14 the introduction of the β‐haloester‐functions moderately reduces the estrogen receptor affinity of 7. However, it was quite strongly diminished in 12. The hydrolytic stability
“部分”抗雌激素2,3-双(2-氟-4-羟基苯基)-2,3-二甲基丁烷的双-丙烯酸酯12、双-β-氯丙酸酯13和双-β-溴丙酸酯14的合成(7) 描述。在 13 和 14 的情况下,β-卤代酯功能的引入适度降低了 7 的雌激素受体亲和力。然而,在 12 中却相当强烈地降低了。体外-受体-测定条件下的水解稳定性依次降低12 14> 13。与7相比,12-14的雌激素效力大大增加。标题化合物对激素依赖性 MXT-M3.2 小鼠乳腺肿瘤产生强烈抑制作用。
