Abstract

Procedure for obtaining acylamine compounds, especially compounds of 7- (N-acylamino) -cef-3-em-4-carboxylic acid of the formula **(See formula)** wherein Ac signifies an acyl group and R2 signifies hydrogen or an organic residue Ra2 which forms together with the group -C (= O) -O a protected carboxyl group, or the salts of such compounds, characterized in that in a compound 7 -amino-cef-3-em of formula **(See formula)** or in a salt of a compound thereof with a salt-forming group, the free amino group is acylated and, if desired, a obtained compound is transformed into another compound of formula I, and/or, if desired, a salt obtained is transformed into a free compound or a free compound obtained in a salt and/or, if desired, a mixture of isomers obtained is separated into the different isomers.
