Here we describe an efficient and cost-effective chemoenzymatic synthesis of the β-lactamase inhibitor avibactam starting from commercially available ethyl 5-hydroxypicolinate hydrochloride. Avibactam was synthesized in 10 steps with an overall yield of 23.9%. The synthetic route features a novel lipase-catalyzed resolution step during the preparation of (2S,5S)-ethyl 5-hydroxypiperidine-2-carboxylate, a valuable precursor of the key intermediate ethyl (2S,5R)-5-((benzyloxy)amino)piperidine-2-carboxylate. Our synthetic route was used to produce 400 g of avibactam sodium salt.

脂肪酶催化拆分在制备（2 S，5 R）-5-（苯甲氧基）氨基）哌啶-2-羧酸乙酯中的应用，β-内酰胺酶抑制剂阿维巴坦的关键中间体

在这里，我们描述了从商业上可获得的5-羟基吡啶甲酸乙酯盐酸盐开始的β-内酰胺酶抑制剂阿维巴坦的高效化学合成方法。阿维巴坦分十步合成，总收率23.9％。合成路线的特点是在制备（2 S，5 S）-5-羟基哌啶-2-羧酸乙酯（关键中间体乙基（2 S，5 R）-5-的有价值的前体）过程中新的脂肪酶催化的拆分步骤（（苄氧基）氨基）哌啶-2-羧酸酯。我们的合成路线用于生产400克阿维巴坦钠盐。
