Abstract
Procedure for obtaining 7-acylamino-cef-3-em-4-carboxylic acid compounds **(See formula)** wherein R1A signifies an Ac acyl group and R1b signifies hydrogen or a methylene moiety, optionally substituted, linked with an amino group existing in the position of the ac acyl moiety and R2 means hydrogen or an organic R2A moiety which together with the group -C (= O) -O- forms a protected carboxyl group, or the salts of such compounds with salt-forming groups, characterized in that in a compound of formula **(See formula)** or in a salt thereof, the free amino group is acylated to an Ac-NH group and, if desired, in a obtained compound, a protected carboxyl group of formula -C (= O) -O-R2A is transformed into the free carboxyl group or other protected carboxyl group of formula -C (= O) -O-R2A and/or, if desired, in a compound obtained, a free carboxyl group is transformed into a protected carboxyl group of formula -C (= O) -O-R2A and/or if desired, in a compound obtained the functional groups protected temporarily during the acylation reaction in the acyl moiety Ac are released and/or, if desired, a compound obtained with an amino group existing in the acyl residue Ac in the α position is reacted with an aldehyde or ketone and/or, if desired, a compound obtained with a salt-forming group is transformed into a salt or a salt obtained in the free compound or in another Salt.
