摘要 (S)-2-氨基-3-乙酰氨基丙酸甲酯是重要的合成砌块,越来越多的研究发现其为具有重要生物学功能的化学骨架。以价廉易得的L-天冬酰胺为起始原料,经Cbz保护、Hofmann重排、酯化、乙酰化、Cbz脱保护5步反应得到重要中间体即目标化合物,总收率达37.5%,其结构经ESI-HRMS、1HNMR和IR确证。 Methyl-(S)-3-acetamido-2-aminopropanoate is an important building block and showed some biological activities in drug discovery.The title compound was synthesized from L-asparagine as the starting material,via a five-step reactions of N-Cbz protection, Hofmann rearrangement, esterification,acetylation and Cbz-deprotection.The overall yield of this important target com- pound was 37.5%.hs structure was confirmed by ESI-HRMS,IHNMR and IR.
