and has been clinically validated as a target by small molecule inhibition for the treatment of a variety of cancers. ABBV-992 (1) was identified as a novel, potent, selective BTK inhibitor and advanced to Phase I clinical trials. An enantioselective synthesis of 1 was developed and scaled to provide 63 g for preclinical characterization. The route features a diazotization enabled by flow chemistry,
布鲁顿酪氨酸激酶 (BTK) 参与 B 细胞受体信号传导,并已被临床验证为小分子抑制治疗多种癌症的靶标。 ABBV-992 ( 1 ) 被确定为一种新型、有效、选择性 BTK 抑制剂,并进入 I 期临床试验。开发了1的对映选择性合成并规模化以提供 63 g 用于临床前表征。该路线的特点是通过流动化学实现重氮化,吡啶酮的新型选择性部分还原,立体选择性埃尔曼亚胺还原,以及在掩蔽丙烯酸酯策略中使用3-氯丙酰氯改进丙烯酰胺的形成。
