Abstract

Abstract : The C–H coupling of arenes with diazo-methylene-diphosphonates enables efficient synthesis of new diphosphonates, which exhibit dual MBL and SBL inhibition. Abstract : We report the highly efficient and scalable Rh(iii )-catalyzed C–H coupling of arenes with diazo-methylene-diphosphonates to give structurally diverse aromatic bisphosphonates in good to excellent yields. These bisphosphonates are one of the very few classes of inhibitors acting against the mechanistically distinct metallo-β-lactamases and serine-β-lactamases and thus represent good starting points for the development of broad spectrum β-lactamase inhibitors.
