Claims
Currently available β-lactamase inhibitors are insufficient to inhibit increasingly complex β-lactamase, and new β-lactamase inhibitors are now required for the difficult treatment of bacterial infectious diseases caused by resistant bacteria that produce class C β-lactamase, extended-spectrum β-lactamase (ESBL) belonging to classes A and D, or class A KPC-2, which still decomposes carbapenems, as a last resort for β-lactam antibiotics. Intermediate compounds of diazabicyclooctane derivatives are provided.
