Structure 3a, a potent angiotensin-converting enzyme inhibitor, was prepared in five steps from L-(+)-alpha-amino-4-phenylbutyric acid by construction of the activated side-chain ester 16, displacement with L-pyroglutamate ester anion, and deblocking. Diastereomer separation was accomplished by chromatography at the diester stage, 17. Pharmacological assays established that 3a parallels enalapril in
通过活化的侧链酯16的构建,由L-(+)-α-氨基-4-苯基丁酸分五个步骤制备结构3a,一种有效的血管紧张素转化酶抑制剂,用L-焦谷氨酸酯阴离子置换,和解块。非对映体的分离是通过在二酯阶段的色谱法完成的。17药理学测定确定3a与依那普利具有抑制转化酶和降低血压的能力。
