paper describes the development of a process to a key steroidal intermediate in fulvestrant, the active pharmaceutical ingredient of the anticancer agent Faslodex. Synthesis of the intermediate, known within AstraZeneca as fulvestrant EAS, involves the copper-catalysed 1,6-conjugate addition of a Grignard reagent to a steroidal dienone. The reaction temperature and the order and rate of addition of
该论文描述了在氟维司群中制备关键甾体中间体的方法的发展,该物质是抗癌药Faslodex的活性药物成分。中间体的合成,在阿斯利康内被称为fulvestrant EAS,涉及将格氏试剂的铜催化的1,6-共轭加成到甾体二烯酮上。反应温度以及试剂的添加顺序和速率对所需化合物的总收率具有显着影响。开发的一个新颖方面是监视与催化循环相关的瞬态颜色变化,这是对过程优化的重要帮助。
