ABSTRACT:
7-Acylamino-desacetoxy-cephalosporanic acid esters are produced by heating a sulfoxide of 6-acylaminopenicillanic acid ester at a temperature of from about 60.degree.C to about 150.degree.C in the presence of a phenol catalyst. The 7-acylamino-desacetoxy-cephalosporanic acid esters produced are known per se and are useful as intermediates for the preparation of desacetoxy-cephalosporin derivatives which exhibit antibacterial activity.
