safety of the chemistry involved. With several steps involving volatile, reactive, and non-UV active materials, reaction optimization was facilitated by implementing off-line 1H NMR analysis of crude mixtures. Key transformations targeted for process development included a Wolff–Kishner reduction, an iridium-catalyzed borylation, and enzymatic resolution of a racemic amino-ester.
以第一代药物化学合成为起点,我们在此描述了AZD4573的工艺开发,这是一种肿瘤学候选药物。除了提高产量和去除色谱步骤之外,我们还解决了其他因素,例如起始材料的可用性以及所涉及的化学物质的安全性。通过涉及挥发性、反应性和非 UV 活性材料的几个步骤,通过对粗混合物进行离线1 H NMR 分析,促进了反应优化。针对工艺开发的关键转化包括 Wolff-Kishner 还原、铱催化的硼化和外消旋氨基酯的酶拆分。
