Abstract Possible structural modifications for increasing the sensitivity of steroid ethers are discussed. 3-Methoxyestra-1, 3, 4 (10)-trien-17-one cyclic ethylene ketal and cyclic ethylene monothioketal suffer cleavage of the ketal ring on exposure to a combination of either lithium aluminum hydride and aluminum trichloride, or diborne and boron trifluoride. The resultant 17μ-(2-hydroxyethyl) ether
摘要 讨论了提高甾体醚敏感性的可能结构修饰。3-Methoxyestra-1, 3, 4 (10)-trien-17-one 环状亚乙基缩酮和环状亚乙基单硫缩酮在暴露于氢化铝锂和三氯化铝或二元和三氟化硼的组合时发生缩酮环裂解. 所得的 17μ-(2-羟乙基) 醚和硫醚已被转化为一系列新的雌激素衍生物,其中几种通过口服给药途径显示出明显的雌激素活性。其他 17-缩酮也发生裂解形成 17μ-醚。
