Abstractl-2-Aminobutyric acid (l-ABA), an unnatural amino acid, is a key intermediate of several important drugs. Although some methods have been developed to prepare pure chiral l-ABA, there are still many drawbacks, including low catalytic efficiency, cumbersome steps and high cost due to the addition of some expensive catalysts or coenzymes. Herein, with chemical and biological approaches together
摘要l-2-氨基丁酸(l-ABA)是一种非天然氨基酸,是几种重要药物的关键中间体。虽然已经开发了一些制备纯手性l-ABA的方法,但由于加入了一些昂贵的催化剂或辅酶,仍存在催化效率低、步骤繁琐和成本高的缺点。在此,我们结合化学和生物学方法,发现了一种新分离的玉米曲霉 ZJUT ZQ013 菌株,该菌株含有微生物脂肪酶,可用于分解外消旋甲基 N-Boc-2-氨基丁酸以产生具有高对映选择性(ees > 99.9)的 l-ABA %,E = 257)。此外,随后的克级实验证实,A. tamarii ZJUT ZQ013 是一种有效制备光学纯酸的有吸引力的生物催化剂。
