La présente invention concerne des dérivés de la famille des céphalosporines, leur procède de préparation et leur application en thdrapeutique,
Les composes selon l'invention répondent à la formule :
dans laquelle
le groupe
en position 4 est un radical acide, ou un sel alcalin ou alcalin terreux ou un sel d'amine, par exemple la triéthylamine ou les 6thanolamines, ou un radical ester facilement hydro lyaable ou méthaboliquement labile et pharmaceutiquement acceptable

Par suite de la présence dans la formule d'un groupement oxime, les composés (I) existent sous 2 formes isomères syn et anti. The present invention relates to derivatives of the cephalosporin family, their preparation process and their application in therapy,
The compounds according to the invention correspond to the formula:

As a result of the presence in the formula of an oxime group, the compounds (I) exist in 2 syn and anti isomeric forms.
Les isomères syn dont l'activité thérapeutique est supérieure sont les composés préférés.The syn isomers whose therapeutic activity is superior are the preferred compounds.
I1 est entendu que les composés (I) indiques ci-dessus peuvent exister
- soit sous la forme indiqueée dans la formule (I),
- soit sous la forme tautomère (I')
dans laquelle A, R1 et R2 ont les significations indiquéez précédemment.It is understood that the compounds (I) indicated above may exist
- in the form indicated in formula (I),
- in the tautomeric form (I ')
wherein A, R1 and R2 have the meanings indicated above.
L'invention concerne également des procédés de prepara- tion des composés de formule (I). The invention also relates to processes for preparing the compounds of formula (I).
Un premier procédé comprend les étapes schématisées ci-après
A first method comprises the steps schematized below
Tri = trityle
On part du sulfoxyde (II) qui par action du composé R2H en solution dans le diméthylformamide en présence d'une base comme la triéthylamine conduit au composé convenablement substitué en position 3 (III). On libère le groupe amino de calui-ci par action du chlorure de thionyle en solution et on isole le composé (IV) sous forme de chlorhydrate. Celui-ci est acylé par le composé (V). Tri = trityle
Starting from sulfoxide (II) which by the action of R2H in solution in dimethylformamide in the presence of a base such as triethylamine leads to the compound suitably substituted in position 3 (III). The amino group is liberated by the action of thionyl chloride in solution and the compound (IV) is isolated as the hydrochloride salt. This is acylated by the compound (V).
Avant d'effectuer la réaction d'acylation, il est souhaitable de substituer le groupe amino de l'acide par un groupe protecteur facile a éliminer ultérieurement. On peut utiliser les groupes habituellement utilisés en synthèse organique pour la protection des groupes aminés et en particulier le groupe trityle. Before carrying out the acylation reaction, it is desirable to substitute the amino group of the acid with a protecting group which is easy to remove later. The groups usually used in organic synthesis for the protection of amino groups and in particular the trityl group can be used.
Pour effectuer la réaction d'acylation, il est nécessaire de procéder à l'activation du groupe carboxyle du composé (V) de pré- férence par transformation en anhydride a l'aide dtun carbodiimlde en général le dicyclohexylcarbodiimide. To carry out the acylation reaction, it is necessary to activate the carboxyl group of the compound (V) preferably by conversion to anhydride using a carbodiimide generally dicyclohexylcarbodiimide.
La réaction d'activation est effectuée au sein d'un solvant organique convenable tel que le tétrahydrofuranne A une tem pérature comprise entre 0 et 500C et de préférence à température ambiante. La réaction d'activation est éventuellement facilitée par addition d'un dérivé hydroxylé tel que l'hydroxy-l benzotriazole. The activation reaction is carried out in a suitable organic solvent such as tetrahydrofuran at a temperature between 0 and 500C and preferably at room temperature. The activation reaction is optionally facilitated by the addition of a hydroxyl derivative such as 1-hydroxybenzotriazole.
La solution du réactif d'acylation ainsi obtenue, ddbar- rassée par filtration de la dicyclohexylurée formée, est ajoutée à une solution du composé (IV) dans un solvant tel que le diméthylformamide. Addition des deux réactifs peut aussi s'effectuer dans l'ordre inverse. The solution of the acylation reagent thus obtained, decarboxed by filtration of the dicyclohexylurea formed, is added to a solution of the compound (IV) in a solvent such as dimethylformamide. Addition of the two reagents can also be done in the reverse order.
Après la réaction d'acylation, le groupe protecteur sur l'amine et l'ester tertiobutylique sont éliminés par un procédé connu, en particulier par hydrolyse en milieu acide en utilisant un acide organique tel que l'acide formique ou l'acide trifluoroacétique. After the acylation reaction, the protecting group on the amine and the tert-butyl ester are removed by a known method, in particular by hydrolysis in an acid medium using an organic acid such as formic acid or trifluoroacetic acid.
En ce qui concerne les matières premières de la réac- tion, les composés (II) et le composé (V) ainsi que ses dérivés dans lesquels le groupe aminé est bloqué par un groupe protecteur sont connus. With regard to the starting materials of the reaction, the compounds (II) and the compound (V) as well as its derivatives in which the amino group is blocked by a protecting group are known.
Une variante de ce procédé consiste å acyler tout d'abord l'amino-7 bromomethyl-3 céphème-3 carboxylate de tertiobutyle-4 (VII) par l'acide (V). On opère ainsi qutil est indiqué pour l'acylation des composés (IV).
A variant of this process consists in acylating, firstly, tert-butyl-4-amino-3-bromomethyl-3-cephem-3-carboxylate (VII) with acid (V). The procedure is as indicated for the acylation of the compounds (IV).
Par action sur le composé (VIII) ainsi obtenu d'un thiol ou d'une amine R2 on obtient le composé (VI) correspondant. On opère dans les conditions indiquées pour l'obtention des composés (III),
Comme indiqué précédemment les composés (VI) traités par un acide fort conduisent aux composés (I). By action on the compound (VIII) thus obtained from a thiol or an amine R2, the corresponding compound (VI) is obtained. The operation is carried out under the conditions indicated for obtaining compounds (III),
As indicated above, the compounds (VI) treated with a strong acid lead to the compounds (I).
Un second procédé de préparation permet d'obtenir les composés (I) à partir du dérivé correspondant non sulfoxydé par action d'un peracide organique tel que l'acide chloro-3 perbenzoique. On opère en solution a température comprise entre 10 et 300 C.
A second preparation process makes it possible to obtain the compounds (I) from the corresponding non-sulfoxidized derivative by the action of an organic peracid such as 3-chloroperbenzoic acid. The solution is operated at a temperature of between 10 and 300.degree.
Parmi les composés (IX) certains sont connus, d'autres ont été décrits dans la demande déposée par la demanderesse le 26 mars 1980 sous le nO 80/06757. Among the compounds (IX) some are known, others have been described in the application filed by the applicant on March 26, 1980 under the number 80/06757.
Les composés (I) de l'invention dans lesquels A est autre que H s'obtiennent à partir des composés (I) dans lesquels A est H par des réactions connues en elles-memes. Compounds (I) of the invention in which A is other than H are obtained from compounds (I) in which A is H by reactions known per se.
Ainsi les sels minéraux sont obtenus par réaction sur les composés (I) dans lesquels A est H d'une base minérale telle que la soude ou la potasse ou le bicarbonate de sodium en quantité dqui- moléculaire ; la réaction de salification est réalisée dans un solvant tel que l'eau ou l'méthanol et le sel obtenu est isolé par évaporation de la solution. Thus, the inorganic salts are obtained by reaction on the compounds (I) in which A is H of a mineral base such as sodium hydroxide or potassium hydroxide or sodium bicarbonate in a quantity of molecular weight; the salification reaction is carried out in a solvent such as water or methanol and the salt obtained is isolated by evaporation of the solution.
Les sels de bases organiques sont obtenus par action, sur une solution de l'acide (I, A=H) dans un solvant ou un mélange de solvants convenable, d'une quantité équimoléculaire de la base organique. Le sel est isolé par précipitation avec l'éther
Les esters sont obtenus par les procédés connus d'estérification ; par exemple on utilisera avantageusement l'action d'un dérivé halogéné sur un sel tel que le sel de sodium de l'acide ; on réalisera de préférence la réaction dans un solvant capable de dissou- dre le dérivé acide de départ par exemple dans le diméthylformamide. The organic base salts are obtained by action, on a solution of the acid (I, A = H) in a solvent or a suitable mixture of solvents, an equimolecular amount of the organic base. The salt is isolated by precipitation with ether
The esters are obtained by known esterification methods; for example, it will be advantageous to use the action of a halogenated derivative on a salt such as the sodium salt of the acid; the reaction is preferably carried out in a solvent capable of dissolving the starting acid derivative, for example in dimethylformamide.
Les isomères de forme syn et anti s'obtiennent par un choix convenable des réactifs. The isomers of syn and anti form are obtained by a suitable choice of reagents.
Les exemples suivants permettent de mieux comprendre la portée de l'invention. The following examples provide a better understanding of the scope of the invention.
Ainsi qu'il est habituel dans cette famille de composés, les produits suivant l'invention ne presentent pas de point de fusion net mais seulement des points de décomposition ne permettant pas de les caractériser. As is customary in this family of compounds, the products according to the invention do not have a net melting point but only decomposition points that do not make it possible to characterize them.
Les produits seront donc caractérisés par leur spectre de résonance magnétique nucléaire enregistré a 60 m Hz, l'étalon interne étant lthexamdthyldisiloxanne. The products will therefore be characterized by their nuclear magnetic resonance spectrum recorded at 60 m Hz, the internal standard being the hexamdthyldisiloxane.

- S : singulet
- D : doublet
- D de D : doublet de doublet
- S. el : singulet élargi
