Abstract

Procedure for obtaining derivatives of 7-aminocephaloesporanic acid of formula I **(See formula)** where X signifies a hydrogen atom or an acyl moiety and R1 signifies a hydrogen atom, a salt-forming cation or OR1 signifies a dissociable substituted methyl ester group, characterized in that compounds of formula II **(See formula)** Where X has the indicated meaning and OR means a dissociable substituted methyl ester group, they are oxidized with aliphatic sulfoxides in the presence of carboxylic anhydrides and, if desired, the obtained compound is transformed into a salt or a salt obtained in another Salt.
