We explored the traceless Staudinger ligation for the functionalization of the C2 position of second generation β-lactamase inhibitors based on a diazabicyclooctane (DBO) scaffold. Our strategy is based on the synthesis of phosphine phenol esters and their ligation to an azido-containing precursor. Biological evaluation showed that this route provided access to a DBO that proved to be superior to commercial
我们探索了用于基于二氮杂双
环辛烷 (DBO) 支架的第二代 β-内酰胺酶抑制剂的 C2 位置功能化的无痕 Staudinger 连接。我们的策略基于膦
酚酯的合成及其与含
叠氮基前体的连接。
生物学评估表明,该途径提供了获得 DBO 的途径,该 DBO 被证明在抑制所测试的五种 β-内酰胺酶中的两种方面优于商业瑞巴坦。
