Carbon and oxygen analogs of penicillin

In accordance with this invention, it has been found that carbon and oxygen analogs of 6β-aminopenicillanic acid and biologically active derivatives thereof can be formed from esters of 6-oxopenicillanic acid. For example, 6β-phenoxyacetoxypenicillanic ac

Process for preparing 7-oxo cephalosporins and 6-oxo penicillins

A process for preparing 7-oxo cephalosporins and 6-oxo penicillins by reaction of a 7-amino cephalosporin or 6-amino penicillin with a carbonyl-containing oxidizing agent is disclosed.
