N-protected α-alkyl-γ-amino-β-keto-esters were synthesized from the corresponding N-urethane protected N-carboxyanhydride (UNCAs) by reaction with lithium enolates in fairly good yields. These compounds are candidates for mimicking the transition state analogue in enzyme inhibitors. They constitute, however, interesting and diverse building blocks for using in combinatorial chemistry.
N-保护的α-烷基-γ-氨基-β-酮酸酯是由相应的N-氨基甲酸酯保护的N-羧基酸酐(UNCA)通过与烯醇锂反应合成的,收率很高。这些化合物是模拟酶抑制剂中过渡态类似物的候选物。但是,它们构成了用于组合化学的有趣且多样化的构建基块。
