A new synthesis of 6-oxopenicillanates by ozonolysis of 6-diazopenicillanates

In this paper we describe a convenient new procedure for preparing 6-oxopenicillanates, via ozonization of the corresponding 6-diazo derivatives.

Method of producing oxo-containing azetidinone compounds

This invention relates to a novel method of producing oxo-containing azetidinone compounds, or salts thereof, or hydrates thereof, said compounds having utility as antimicrobial agents and as intermediates for the synthesis of other azetidinone compounds having antimicrobial activity.

An Efficient Synthesis of 6-Oxopenicillanic and 7-Oxocephalosporanic Acid Derivatives

Trifluoromethanesulphonation of benzyl 6-aminopenicillanate (3) and the 7-aminocephalosporanates (7a-c) with (CF3SO2)2O gave the bis(trifluoromethylsulphonate) derivatives (5) and (8a-c), which were then converted into the imines (6) and (9a-c) by treatme

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
