allophenylnorstatine [Apns; (2S, 3S)‐3amino‐2‐hydroxy‐4‐phenylbutyric acid] as a transition state mimic at the scissile bond were designed and synthesized in the hope of obtaining a novel KNI series of HIV protease inhibitors. The precursors, N‐P2′‐3‐(2S, 3S)‐3‐(tert‐butyloxy‐carbonyl)amino‐2‐hydroxy‐4‐phenylbutanoyl)‐5, 5‐dimethylthiazolidine‐4‐carboxamide (N‐Boc‐Apns‐Dmt‐P2′) 4a–p were prepared by deprotection
结合别苯去甲司他汀的二肽类似物 [Apns; (2S, 3S) -3amino-2-hydroxy-4-phenylbutyric acid]作为易断键处的过渡态模拟物被设计和合成,希望获得新型 KNI 系列 HIV 蛋白酶抑制剂。前体,N-P2'-3-(2S,3S)-3-(叔丁氧基-羰基)氨基-2-羟基-4-苯基丁酰基)-5,5-二甲基噻唑烷-4-甲酰胺(N-Boc- Apns - Dmt - P2 ') 4a - p 通过合成酮 N - P2 ' - (叔丁氧羰基) - 5, 5 - 二甲基噻唑烷 - 4 - 甲酰胺 (Boc - Dmt - P2 ') 2a - p 的脱保护制备,然后与 (2S, 3S) 3- (叔丁氧羰基) 氨基- 2- 羟基- 4- 苯基丁酸 (N - Boc - Apns - OH) 偶联 3. 脱保护的中间体 4 与 P2 配体的活化羧基偶联以提供目标二肽。在这项工作中,我们在
