It is understood that the products of formula I can exist either in the form indicated by formula I or in the form of products of the formula ##STR10## in which A, A', R.sub.1, R.sub.b and R.sub.c have the above meanings.

The novel process of the invention for the preparation of a compound of formula I comprises reacting a compound of the formula ##STR11## racemic or optically active syn isomer or a functional derivative thereof in which R.sub.a is hydrogen or a protective group of the amino, R.sub.b and R.sub.c are individually hydrogen or a protective group of the hydroxyl, R.sub.d is hydrogen or the remainder of an easily eliminatable ester group with a compound of the formula ##STR12## in which Hal is halogen, A" is hydrogen or the remainder of an easily eliminatable ester group and the wavy line indicates that the CH.sub.2 Hal can be found in the E or Z position to obtain a compound of the formula ##STR13## reacting the latter with a reagent capable of introducing R.sub.1 to obtain a compound of the formula ##STR14## which is optionally separated into its E or Z isomers or the Z isomers are converted into E isomers and subjecting the products of formula V, if necessary or if desired, to one or more of the following reactions in any order;

a) cleaving by hydrolysis or by the action of thiourea of all or part of the ester groups or protective groups of the amino or the hydroxyl,

b) esterification or salification of the carboxylic(x) by a base,

c) salification f the amino by an acid,

d) separation of the products in the form of an R, S mixture into R or S.

Reagents capable of introducing R.sub.1 include either when R.sub.1 is a quaternary ammonium, a reagent composed of the R.sub.1 itself, this not being in the form of quaternary ammonium. If one wishes to introduce a pyridinium, the operation will be done with pyridine, or when R.sub.1 is ##STR15## a reagent corresponding respectively to ##STR16## or preferably its sodium salt.

Among the preferred reagents are those of the formulae ##STR17##

In addition to the groups mentioned above, the easily eliminable esters groups of A" and R.sub.d may be, for example, the ester formed with the following; butyl, isobutyl, tert-butyl, pentyl, hexyl, acetoxymethyl, propionyloxymethyl, butyryloxymethyl, valeryloxymethyl, pivaloyloxymethyl, 2-acetoxyethyl, 2-propionyloxyethyl and 2-butyryloxyethyl or 2-iodoethyl, 2,2,2-trichloroethyl, vinyl, allyl, ethynyl, propynyl, benzyl, 4-methoxybenzyl, 4-nitrobenzyl, phenethyl, trityl, diphenylmethyl, 3,4-dimethyloxyphenyl, phenyl, 4-chlorophenyl, tolyl, tert-butylphenyl. Diphenylmethyl is preferred for R.sub.d and 4-methoxybenzyl or diphenylmethyl is preferred for A".

The protective group of the amino radical which is R.sub.a can be alkyl of 1 to 6 carbon atoms such as preferably, tert-butyl or tert-amyl. R.sub.a can also be aliphatic, aromatic or heterocyclic acyl or carbamoyl. The lower alkanoyl groups can be formyl, acetyl, propionyl, butyryl, isobutyryl, valerly, isovaleryl, oxalyl, succinyl, pivaloyl.

R.sub.a can also be lower alkoxy or cycloalkoxycarbonyl such as methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, 1-cyclopropylethoxycarbonyl, isopropyloxycarbonyl, butyloxycarbonyl, tert-butyloxycarbonyl, pentyloxycarbonyl, hexyloxycarbonyl, benzoyl, toluolyl, naphthoyl, phthaloyl, mesyl, phenylacetyl, phenylpropionyl and aralkoxycarbonyl such as benzyloxycarbonyl.

The acyl groups can be substituted by chlorine, bromine, iodine or fluorine such as chloroacetyl, dichloroacetyl, trichloroacetyl, bromoacetyl or trifluoroacetyl.

R.sub.a can also be lower aralky such as benzyl, 4-methoxybenzyl, phenethyl, trityl, 3,4-dimethoxybenzyl or benzhydryl or haloalkyl such as trichloroethyl or chlorobenzoyl, p-nitrobenzoyl, p-tert-butylbenzoyl, phenoxyacetyl, caprylyl, n-decanoyl, acryloxy or trichloroethoxycarbonyl.

R.sub.a can also be methylcarbamoyl, phenylcarbamoyl, naphthylcarbamoyl as well as the corresponding thiocarbamoyls. Trityl is preferred. The above list is not limitative and it is obvious that other amine protective groups, particularly groups known in the chemistry of peptides, can also be used.

The protective group of the hydroxyl which can be R'.sub.b and R'.sub.c can be chosen from the list below: R'.sub.b and R'.sub.c can be acyl such as formyl, acetyl, propionyl, chloroacetyl, bromoacetyl, dichloroacetyl, trichloroacetyl, trifluoroacetyl, methoxyacetyl, phenoxyacetyl, benzoyl, benzoylformyl, p-nitrobenzoyl or ethoxycarbonyl, methoxycarbonyl, propoxycarbonyl, 2,2,2-trichloroethoxycarbonyl, benzyloxycarbonyl, tert-butoxycarbonyl, 1-cyclopropylethoxycarbonyl, tetrahydropyrannyl, tetrahydrothiopyrannyl, methoxytetrahydropyrannyl, trityl, benzyl, 4-methoxybenzyl, benzylhydryl, trichloroethyl, 1-methyl-1-methoxyethyl, phthaloyl. Other acyls are butyryl, isobutyryl, valeryl, isovaleryl, oxalyl, succinyl and pivaloyl.

Also useful are phenylacetyl, phenylpropionyl, mesyl, chlorobenzoyl, p-nitrobenzoyl, p-tert-butylbenzoyl, caprylyl, acryloyl, methylcarbamoyl, phenylcarbamoyl, naphthylcarbamoyl or alkoxy alkoxymethyl such as methoxyethoxymethyl.

OR'.sub.b or OR'.sub.c can also form with the phenyl to which they are attached groups such as ##STR18## Methoxyethoxymethyl is preferred for substituents R'.sub.b and R'.sub.c.

In a method for implementing the process, a functional derivative of the product of formula II is reacted with functional derivative can be a halide, a symmetrical or mixed anhydride an amide, an azide or an activated ester. Examples of a mixed anhydride are those formed with isobutyl chloroformate and with pivaloyl chloride and the carboxylic-sulfonic mixed anhydrides formed, with p-toluene sulfonyl chloride.

An example of an activated ester is the ester formed with 2,4-dinitrophenol and with hydroxybenzothiazole. An example of the halide is acid chloride or bromide. The anhydride can be formed in situ by reaction of N,N'-disubstituted carbodiimide such as N,N-dicyclohexycarbodiimide.

The acylation reaction preferably takes place in an organic solvent such as methylene chloride but other solvents such as tetrahydrofuran, chloroform or dimethylformamide may be used. When an acid halide is used, generally when an acid halide molecule is released during the reaction, the reaction is preferably carried out in the presence of a base such as sodium hydroxide, potassium hydroxide, sodium or potassium carbonate and bicarbonate, sodium acetate, triethylamine, pyridine, morpholine or N-methylmorpholine. The reaction temperature is generally lower or equal to ambient temperature.

Also a product of formula II can be reacted directly with a product of formula III in the presence of a carbodiimide such as diisopropylcarbodiimide.

The reaction of the reagents capable of introducing R.sub.1 into the product of formula IV is carried out under the following conditions: When Hal is chlorine, a substitution of the chlorine by iodine in the presence of sodium iodide can be carried out in situ or separately and then the desired reagent is added, either in the presence or not of an organic solvent such as acetonitrile or tetrahydrofuran. The desired reagent can also be reacted in the presence of silver tetrafluoroborate on the product of formula IV in which Hal is chlorine.

The isomerism of the products of formula V can be different than that of the products of formula IV used at the start. In the case where the Z isomer is isolated, this isomer can be converted into the E isomer by known methods, preferably by the action of iodine.

Depending upon the values of R.sub.a, R'.sub.b, R'.sub.c, R.sub.d and A", the products of formula V can or cannot constitute the products of formula I. The products of formula V constitute the products of formula I when R.sub.a is hydrogen, when R'.sub.b and R'.sub.c are not a protective group of the hydroxyl that one wishes to eliminate, namely when R'.sub.b and/or R'.sub.c is acyl and when R.sub.d and A" are not among the easily cleavable ester groups, one of those that one would wish to eliminate.

In other cases, the action on the product of formula V of one or more hydrolysis agents, hydrogenolysis agents or thiourea has the object of eliminating R.sub.a when it is a protective group of the amino, of eliminating the R'.sub.b and R'.sub.c when these are protective groups of the hydroxyl and/or of eliminating the R.sub.3 and A" when these are among the easily cleavable esters of those that one wishes to eliminate.

However, it is of course possible to eliminate R.sub.a, R'.sub.b and R'.sub.c without touching substituents R.sub.d and A" when these must be preserved. This is the case, for example, when A" is an ester group that is to be preserved such as propionyloxymethyl. The nature of the reagents brought into play in such a case is well known to one skilled in the art. For example, a description of the various elimination methods of the different protective groups will be found in French Patent Application No. 2,499,995.

Given that the preferred protective groups used are trityl for R.sub.a, methoxyethoxymethyl for R'.sub.b and R'.sub.c, diphenylmethyl for R.sub.d and 4-methoxybenzyl or diphenylmethyl for A", trifluoroacetic acid without a solvent or in a solvent such as anisole or a mixture of solvents such as anisole/methylene chloride is preferably used. A salt is then obtained with trifluoroacetic acid and return to the free base can be effected by the action of a base such as triethylamine carbonate.

The salification of the products can be carried out according to usual methods. Salification can be obtained by the action of a mineral base such as sodium hydroxide or potassium hydroxide, sodium or potassium carbonate or bicarbonate on a product in acid form or on a solvate, for example, the ethanolic solvate or hydrate of this acid. Mineral acid salts such as trisodium phosphate can also be used as well as organic acid salts.

Examples of organic acid salts are sodium salts of aliphatic, linear or branched, saturated or unsaturated carboxylic acids with 1 to 18 carbon atoms and preferably with 2 to 10 carbon atoms. The aliphatic chains of these acids can be interrupted by one or more heteroatoms such as oxygen or sulfur or substituted by aryl such as phenyl, thienyl, furyl, by one or more hydroxyl or by one or more halogens such as fluorine, chlorine or bromine, preferably chlorine, by one or more carboxylic or lower alkoxycarbonyl, preferably methoxycarbonyl, ethoxycarbonyl or propyloxycarbonyl, by one or more aryloxys, preferably phenoxy.

Furthermore, as organic acids, sufficiently soluble aromatic acids can be used such as substituted benzoic acids, preferably substituted by lower alkyl radicals. Examples of such organic acids are formic acid, acetic acid, butyric acid, adipic acid, isobutyric acid, n-caproic acid, isocaproic acid, chloropropionic acid, crotonic acid, phenylacetic acid, 2-thienylacetic acid, 3-thienyl-acetic acid, 4-ethylphenylacetic acid, glutaric acid, the monoethylic ester of adipic acid, hexanoic acid, heptanoic acid, decanoic acid, oleic acid, stearic acid, palmitic acid, 3-hydroxypropionic acid, 3-methoxypropionic acid, 3-methoxythiobutyric acid, 4-chlorobutyric, 4-phenylbutyric acid, 3-phenoxybutyric acid, 4-ethylbenzoid acid, 1-propylbenzoic acid. However, sodium acetate, sodium 2-ethyl hexanoate or sodium diethyl acetate are preferably used as sodium salts.

Salification can also be obtained by the action of an organic base such as triethylamine, diethylamine, trimethylamine, propylamine, N,N-dimethylethanolamine, tris[(hydroxymethyl)-amino]-methane, methylamine, ethanolamine, pyridine, picoline, dicyclohexyl amine, morpholine and benzylamine or by the action of arginine, lysine, procaine, histidine, N-methyl glucamine. This salification is preferably carried out in a solvent or a mixture of solvents such as water, ethyl ether, methanol, ethanol or acetone.

The salts are obtained in amorphous or crystallized form according to the reaction conditions employed. Crystallized salts are prepared preferably by reacting free acids with one of the salts of the aliphatic carboxylic acids mentioned above, preferably with sodium acetate. The salification of products by mineral or organic acids is carried out in the usual conditions.

The optional esterification of products is carried out under standard conditions, generally by reacting the acid of formula I or a functional derivative thereof with a derivative of the formula

Z--Re in which Z is hydroxyl or halogen such as chlorine, bromine, iodine and Re is the ester group to be introduced, a non-exhaustive list of which groups is given above. In some cases, it can e advantageous to carry out an esterification on a product whose amine and/or reactive groups which are present on the oxyimino are blocked before removing the protective group of the amine and the reactive group which are present on the oxyimino.

The products of formula I comprise several asymmetrical carbons. In the cephem nucleus which comprises two asymmetrical carbons, the two carbons are in R configuration. Furthermore, the group present on the oxyimino function also has an asymmetrical carbon; ##STR19## which can be in R or S form or in the form of an R, S mixture. The separation of the two diastereoisomers can be carried out by ways known to one skilled in the art, for example, by chromatography.

The novel antibiotic compositions of the invention are comprised of an antibiotically effective amount of at least one compound of formula I and its non-tox, pharmaceutically acceptable acid addition salts and an inert pharmaceutical carrier. The compositions may be in the form of tablets, dragees, capsules, granules, suppositories, ointments, creams, gels and injectable preparations.

Examples of suitable excipients are lactose, starch, magnesium stearate, cocoa butter, aqueous or non-aqueous vehicles, fatty substances of animal or vegetable origin, paraffin derivatives, glycols, various wetting, dispersing or emulsifying agents, preservatives.

These compositions can preferably be in the form of a powder to be dissolved extemporaneously in an appropriate vehicle, for example, apyrogenic sterile water.

The compositions are effective against gram (+) bacteria such as staphylococcus, streptococcus and notably on penicillin-resistant staphylococcus. Their effectiveness against gram (-) bacteria notably on coliform bacteria, klebsiella, salmonella, proteus and pseudomonas, is particularly remarkable.

These compositions are useful in the treatment of affections caused by sensitive germs and notably in that of staphylococcis such as staphylococcus septicemia, malignant staphylococcis of the face or skin, pyodermitis, septic or suppurating wounds, anthrax, phlegmons, erysipelas, acute primitive or post-influenza staphylococcis, bronchopneumonia, lung suppurations as well as in the treatment of colibacillosis and associated infections, in infections due to proteus, klebsiella and salmonella and in other affections caused by gram (-) bacteria. The compositions may also be used on disinfectants for surgical instruments.

The novel method of the invention for treating bacterial infections in warm-blooded animals, including humans, comprises administering to warm-blooded animals an antibiotically effective amount of at least one compound of formula I and its non-toxic, pharmaceutically acceptable acid addition salts. The compounds may be administered buccally, rectally, parenterally preferably intramuscularly or topically to the skin or mucous membranes. The usual daily dose is 3.33 to 53.33 mg/kg depending on the condition treated, the compound used and the method of administration. For example, the compound of Example 1 may be administered at a dose of 0.250 to 4 g per day orally or 0.500 to 1 g three times a day intra-muscularly.

The novel intermediate products of the invention are the compounds of formula IV and formula V in which R.sub.a is a protective group of the amino, formulae IV and V being as defined above.

The products of formula II are known from the literature i.e. European Patent Applications No. 0,238,061 or No. 0,266,060 or can be prepared by known methods. The products of formula III are also known from the literature, i.e. British Patent Application No. 2,134,522 or German Patent No. DE 3,512,225.

In the following examples there are described several preferred embodiments to illustrate the invention. However, it should be understood that the invention is not intended to be limited to the specific embodiments.
