Herein, we have described a novel and concise synthesis of the potent angiotensin-converting enzyme (ACE) inhibitor, benazepril hydrochloride (7) in trifluoroethanol via an Ugi three-component reaction in shorter reaction times. The key step is the trifluoroacetic acid-mediated hydrolysis of secondary amides (4a and 4b) followed by esterification as a domino process to form corresponding ethyl ester
在这里,我们已经描述了一种有效的血管紧张素转化酶(ACE)抑制剂贝那普利盐酸盐(7)在三氟乙醇中通过Ugi三组分反应在较短的反应时间内合成的新方法。关键步骤是三氟乙酸介导的仲酰胺(4a和4b)的水解,然后进行酯化反应(作为多米诺骨牌工艺)以形成相应的乙酯(6)。主要使用两种通用的可转换异氰酸酯(1a和1b)合成盐酸贝那普利。 图形摘要 简介:使用Ugi三组分反应可高效合成盐酸贝那普利。
