ABSTRACT:
The present invention relates to a process for the production of substituted 5-isoxazolidinone antibiotics. More specifically the patent relates to the production of compounds that mimic the antibiotic action of β-lactams, are resistant to β-lactamase degradation, and inhibit all classes of β-lactamase.
