A homo-chiral synthesis of (7R,8aS)-octahydro-5,5-dimethylindolizin-7-amine 8 and (7S, 8aS)-octahydro-5,5-dimethylindolizin-7-ol 9, amine building blocks which have found applications within the pharmaceutical industry, is presented. The approach uses a Novozym 435-mediated kinetic resolution of racemic octahydroindolizine (indolizidine) alcohol 13 as a key step (up to 100 g scale).
(7的HOMO-手性合成- [R,8α小号) -八氢-5,5-二dimethylindolizin -7-胺8和(7小号,8α小号) -八氢-5,5-二dimethylindolizin -7-醇9,胺建筑介绍了已在制药行业中找到应用的模块。该方法使用Novozym 435介导的外消旋八氢吲哚嗪(吲哚并立定)醇13的动力学拆分作为关键步骤(最大量为100 g)。
