A method is disclosed for preparing a synthetic intermediate for treprostinil via a stereoselective alkyne addition reaction using a chiral inducing agent. Also described are methods of preparing treprostinil or a pharmaceutically acceptable salt thereof comprising the alkyne addition reaction as well as novel intermediates useful for synthesis prostacyclin derivatives. A functional alcohol protecting group protects the alcohol group from participating in reactions that are occurring in other parts of the molecule. The intermediate is later deprotected prior to conversion and hydrolyzing to obtain the final treprostinil product.
揭示了一种通过使用手性诱导剂进行立体选择性炔基加成反应来制备曲前列素的合成中间体的方法。还描述了通过炔基加成反应制备曲前列素或其药用可接受盐的方法,以及用于合成前列环素衍生物的新型中间体。功能醇保护基保护醇基,使其不参与分子其他部分正在发生的反应。在转化和水解之前,中间体稍后被去保护以获得最终的曲前列素产品。
