Amino-beta-lactamic acid salts, having the formula:
wherein: (X-Y) may form a system having from 1 to 3 carbon atoms, with or without double bond, a) closed, in which: X is an atom selected from among carbon, oxygen, nitrogen and sulphur; Y is methylene; Z is a carboxy, sulphonic or phosphonic group. b) open, which may comprise a double bond, in which: X is an atom of hydrogen or a methyl, hydroxymethyl or thiol group, Y is an acid radical chosen from the group formed by sulphonic, phosphonic and sulphoamidic acid; Z is missing. R is an atom or hydrogen, or a methoxyl or ethoxyl group. R is, when present, methyl, acetoxymethyl, acylthiomethyl, such as acetyl and benzoyl derivatives, methoxy, chlorine, carbamoyloxymethyl, azido, azidomethyl (alpha, beta)-thioethylamine or a thiomethyl-heterocyclic derivative of the thiazole, thiadiazole, triazole, tetrazole, oxazole, oxadiazole, pyrimidine and imidazole nuclei. R2 is an atom of hydrogen or a methyl, ethyl, benzyl or aryl group. m, n may be the same or different and may range from 1 to 4, forming a ring or m = n = 0 to form an open chain. A process for their preparation is also disclosed.
