bacteria. Due to its promising activity but lack of chemical stability, thienamycin serves as inspiration for new synthetic antibiotic scaffolds. In this study, we report a nine-step enantioselective formal synthesis of thienamycin. Our route utilizes an asymmetric reduction, enabled by NaBH and -tartaric acid, followed by a series of diastereoselective reactions to access the key azetidinone precursor to
硫霉素是一种碳青霉烯类抗生素,对革兰氏阴性和革兰氏阳性细菌具有有效的活性。由于其具有良好的活性但缺乏化学稳定性,硫霉素成为新型合成抗生素支架的灵感来源。在这项研究中,我们报告了硫霉素的九步对映选择性正式合成。我们的路线利用 NaBH 和酒石酸实现的不对称还原,然后进行一系列非对映选择性反应,以获得硫霉素的关键氮杂环丁酮前体。这种氮杂环丁酮前体可用作进一步开发和扩大下一代 β-内酰胺抗生素支架范围的中间体。
