摘要:
The process comprises a series of stages essentially comprising the protection of the functional groups of the side chain of Ampicillin, esterification of the acid group, oxidation to sulphoxide, expansion of the thiazole ring to a thiazine ring, ozonolysis of the exomethylene cefam derivative obtained, substitution of the hydroxyl group by chlorine and de-protection of the functional groups, in which the order of some stages can be varied without affecting the final result.
