5-substituted 3-pyrrolin-2-ones bearing l-Ile-l-Pro-OH or l-Phe-NHCH2Ph were successfully synthesized by utilizing a characteristic reaction cascade based on alkaline hydrolysis of the corresponding diethyl α-hydroxy-α-(β-propiolamide)malonates. Among the synthesized chiral pyrrolinones, compound 5S-9 proved to be the most potent inhibitor against cathepsin B.
通过基于相应的二乙基α-羟基-碱性水解的特征反应级联反应,成功合成了带有1-Ile-1-Pro-OH或1-Phe-NHCH 2 Ph的手性5-取代的3-吡咯啉-2-酮α-(β-丙酰胺)丙二酸酯。在合成的手性吡咯烷酮中,化合物5 S - 9被证明是对组织蛋白酶B最有效的抑制剂。
