The synthesis of four new isomers of estradiol in which the ring A to ring C planes are perpendicular to each other as a result of a spiro BC ring junction is described. Heterocyclic analogs and carbocyclic homologs of these compounds are also reported. Estrogen receptor binding studies show that the spiro compounds with the natural stereochemistry at C9 bind almost as strongly as estradiol but with
描述了四个新的雌二醇异构体的合成,其中由于螺环BC环连接,环A到环C的平面彼此垂直。还报道了这些化合物的杂环类似物和碳环同源物。雌激素受体结合研究表明,在C9处具有自然立体化学的螺环化合物几乎与雌二醇一样强地结合,但对β的选择性更高。这些研究表明,雌激素受体可以很容易地容纳与天然配体具有明显不同固定形状的雌激素异构体
