methodology was a key tool used to produce a synthesis intermediate with high optical purity. In addition, developing a tandem Mannich–aza-Michael reaction to obviate the need for a Curtis/acylation sequence and a novel reductive amination/thermal lactamization to circumvent Freidinger-type pyrrolidone preparation are some of the synthesis improvements that enabled access to the target molecule to
BMS-813160 是 Bristol Myers Squibb 目前正在开发的制药实体。它的定义结构特征是独特的手性全顺式三氨基环己烷核心。BMS 的药物和工艺化学小组之前已经发布了与目标分子相似的化学型的合成策略,但需要一种适合长期供应的简化方法。一种新的合成路线被概念化,实验研究,并确定满足效率标准,解决了以前方法的关键限制。采用/优化 Trost 不对称烯丙基胺化去对称化方法是用于生产具有高光学纯度的合成中间体的关键工具。此外,
