The first total syntheses of izenamides A, B, and C, which are depsipeptides inhibitor of cathepsin D, were accomplished. In addition, the stereochemistry of izenamide B was confirmed by our syntheses. The key features of our synthetic route involve the avoidance of critical 2,5-diketopiperazine (DKP) formation and the minimization of epimerization during the coupling of amino acids for the target
完成了组织蛋白酶 D 的缩肽抑制剂 izenamides A、B 和 C 的首次全合成。此外,我们的合成证实了 izenamide B 的立体化学。我们合成路线的主要特点包括避免关键的 2,5-二酮哌嗪 (DKP) 形成和在目标肽的氨基酸偶联过程中尽量减少差向异构化。
