CEFATRIAXONE - Preparation Method

Open Data Verified Data

using 7-ACA (7-aminocephalosporanic acid) as raw material, 7-ACT was synthesized by cyclocondensation with triazine, followed by active ester of amidoxime (phosphorus-containing active ester or mercapto heterocyclic active ester). The condensation forms the cephalosporins. When using the phosphorus-containing active ester, the carboxyl group and hydroxyl group on the 7-ACT must be protected by a silylating reagent such as mono-trimethylacetamide or BIS-methylsilylurea, and its condensation product is ceftriaxone acid, ceftriaxone disodium salt can only be formed by salt formation reaction. When the mercapto heterocyclic active ester is used, the carboxyl group does not need to be protected in advance, and the condensation product forms a salt in one step, so the industry is simpler.
