Process research and development of the fully synthetic broad spectrum tetracycline TP-2758, with a chiral pyrrolidine side chain at the C-8 position, is described. The process utilizes two key intermediates, 7 and 10, in a convergent approach that allows for manufacturing of sufficient quantities of API to supply preclinical and early clinical development. The pyrrolidine moiety was introduced into
描述了在C-8位带有手性吡咯烷侧链的全合成广谱四环素TP-2758的工艺研究和开发。该过程以一种融合的方法利用了两个关键的中间体7和10,该中间体允许制造足够数量的API以提供临床前和早期临床开发。使用Ellman的亚磺酰胺化学将吡咯烷部分以高对映选择性引入到左手部分(LHP)10中,并且通过X射线晶体结构分析确认了绝对构型。
