significant threat in clinical therapy. Among them, Klebsiella pneumoniae clinical isolates overexpressing KPC‐2 carbapenemase are the most worrisome, extending bacterialresistance to last‐resort carbapenems. In this study, we investigate the molecular recognition requirements in the KPC‐2 active site by small phenylboronicacidderivatives. Four new phenylboronicacidderivatives were designed and tested
