Abstract

Procedure for obtaining 7-amino-3-cephem-3-ol-4-carboxylic acid or substituted compounds, of formula **(See formula)** wherein RA1 represents a protective amyrium group and RB1 represents hydrogen or an acyl group Ac, or RA1 and RB1 together represent a bivalent protective amino group, R2 represents hydroxy or a residue which together with the carbonyl group -C (= O) - forms a protected carboxyl group, and R3 signifies a hydrocarbon moiety, optionally substituted, or an acyl group, or the salts of such compounds with salt-forming groups, characterized in that as such a 7-ami-non-cephem acid compound -4-carboxylic formula **(See formula)** or in a salt of a compound thereof, the free amino group at position 7 is converted into a protected amino group and a compound obtained of formula I is optionally isolated as a salt.
