    名称:
    一种替勃龙的制备方法
    摘要:
    本发明公开了一种替勃龙的制备方法,属于甾体激素药物的制备加工技术领域。该方法以6,7‑二脱氢炔诺酮为起始原料,经过格氏、双醚化和水解反应,制备得到替勃龙。本发明合成路线中格氏反应步骤引入7‑甲基步骤,无需对17‑位羟基进行特殊保护,反应得到7α‑甲基中间体和7β‑甲基异构体比例大于20:1,不需要经过色谱分离,通过简单处理就可以得到所需单一7α‑甲基中间体,提纯过程简单,最终产品纯度达到99.0%以上,产率高于60%;所用原料价廉易得,反应步骤少,反应条件温和、安全,容易控制操作;反应所用试剂环境污染小,具有良好的经济和社会效益。
