cancer-associated death. Herein, we report two new synthetic routes for synthesizing the target compound through four consecutive steps, using a Weinreb amide approach starting from a common 3-bromobenzoyl chloride. A key step in the approach is a coupling reaction of a readily available Grignard reagent with amide 4 to produce 6, a previously unreported coupling pattern. These new strategies offer an efficient and
KGP94 是溶酶体内肽酶 (Cathepsin L) 的强效、选择性和竞争性抑制剂,目前正在临床前试验中用于治疗转移性癌症,这是癌症相关死亡的主要原因。在此,我们报告了通过四个连续步骤合成目标化合物的两条新合成路线,使用 Weinreb 酰胺方法,从常见的 3-溴苯甲酰氯开始。该方法的一个关键步骤是易于获得的格氏试剂与酰胺4的偶联反应,以产生6,这是一种以前未报道的偶联模式。这些新策略提供了一种有效的替代方法来合成具有优异总产率的目标化合物。
