Heterocyclylalkylpiperidine derivatives, their preparation and compositions containing them

[0002] The present invention relates to heterocyclylalkyl-piperidine derivatives of general formula:

[0003] which are active as antimicrobial agents. The invention also relates to their preparation and to compositions containing them.

[0004] Patent applications WO 99/37635 and WO 00/43383 disclose antimicrobial quinolylpropylpiperidine derivatives of general formula:

[0005] in which the radical R1 is especially (C1-6) alkoxy, R2 is hydrogen, R3 is in position −2 or −3 and represents (C1-6) alkyl which may optionally be substituted with from 1 to 3 substituents chosen from thiol, halogen, alkylthio, trifluoromethyl, carboxyl, alkyloxycarbonyl, alkylcarbonyl, alkenyloxycarbonyl, alkenylcarbonyl, hydroxyl optionally substituted with alkyl, etc., R4 is a group —CH2—R5 for which R5 is selected from alkyl, hydroxyalkyl, alkenyl, alkynyl, tetrahydrofuryl, optionally substituted phenylalkyl, optionally substituted phenylalkenyl, optionally substituted heteroarylalkyl, optionally substituted heteroaryl, etc., n is 0 to 2, m is 1 or 2 and A and B are especially oxygen, sulfur, sulfinyl, sulfonyl, NR11, CR6R7 for which R6 and R7 represent H, thiol, alkylthio, halo, trifluoromethyl, alkenyl, alkenylcarbonyl, hydroxyl, amino, and Z1 to Z5 are N or CR1a, etc.

[0006] These products show antimicrobial activity. However, no derivative disubstituted in position −4 of the piperidine had been synthesized hitherto and consequently no biological activity had been discovered for such products either.

[0007] Since slight modifications to the structures already known can result in large variations in activity, it was not obvious that derivatives disubstituted in position −4 of the piperidine would also have antibacterial activity.

[0008] European patent application EP 30044 discloses quinoline derivatives which are useful as cardiovascular agents, corresponding to the general formula:

[0009] in which R1 is especially alkyloxy, A-B is —CH2— CH2—, —CHOH—CH2—, —CH2—CHOH—, —CH2—CO— or —CO—CH2—, R1 is H, OH or alkyloxy, R2 is ethyl or vinyl, R3 is especially alkyl, hydroxyalkyl, cycloalkyl, hydroxyl, alkenyl, alkynyl, tetrahydrofuryl, phenylalkyl, optionally substituted diphenylalkyl, optionally substituted phenylalkenyl, optionally substituted benzoyl or benzoylalkyl, optionally substituted heteroaryl or heteroarylalkyl, and Z is H or alkyl or forms with R3 a cycloalkyl radical.

[0014] R3 represents a phenyl, mono- or bicyclic aromatic heterocyclyl or alk-R°3 radical for which alk is an alkyl radical and R°3 represents hydrogen, halogen, hydroxyl, alkyloxy, alkylthio, alkylsulfinyl, alkylsulfonyl, alkylamino, dialkylamino, cycloalkyl, cycloalkyloxy, cycloalkylthio, cycloalkylsulfinyl, cycloalkylsulfonyl, cycloalkylamino, N-cycloalkyl-N-alkylamino, —N-(cycloalkyl)2, acyl, cycloalkylcarbonyl, phenyl, phenoxy, phenylthio, phenylsulfinyl, phenylsulfonyl, phenylamino, N-alkyl-N-phenylamino, N-cycloalkyl-N-phenylamino, —N-(phenyl)2, phenylalkyloxy, phenylalkylthio, phenylalkylsulfinyl, phenylalkylsulfonyl, phenylalkylamino, N-alkyl-N-phenylaminoalkyl, N-cycloalkyl-N-phenylalkylamino, benzoyl, mono- or bicyclic aromatic heterocyclyl, heterocyclyloxy, heterocyclylthio, heterocyclylsulfinyl, heterocyclylsulfonyl, heterocyclylamino, N-alkyl-N-heterocyclylamino, N-cycloalkyl-N-heterocyclylamino, heterocyclylcarbonyl, heterocyclylalkyloxy, heterocyclylalkylthio, heterocyclylalkylsulfinyl, heterocyclylalkylsulfonyl, heterocyclylalkylamino, N-alkyl-N-heterocyclylaminoalkyl, N-cycloalkyl-N-heterocyclylaminoalkyl, (the heterocyclyl portions mentioned above being mono- or bicyclic aromatic), carboxyl, alkyloxycarbonyl, —NRaRb or —CO—NRaRb for which Ra and Rb are defined as above in the definition of R2, or alternatively R°3 represents —CR′b=CR′c-R′a for which R′a represents phenyl, phenylalkyl, heterocyclyl or heterocyclylalkyl in which the heterocyclyl portion is mono- or bicyclic aromatic, phenoxyalkyl, phenylthioalkyl, phenylsulfinylalkyl, phenylsulfonylalkyl, phenylaminoalkyl, N-alkyl-N-phenylaminoalkyl, heterocyclyloxyalkyl, heterocyclylthioalkyl, heterocyclylsulfinylalkyl, heterocyclylsulfonylalkyl, heterocyclylaminoalkyl, N-alkyl-N-heterocyclylaminoalkyl, heterocyclylthio, heterocyclylsulfinyl, heterocyclylsulfonyl, (the heterocyclyl portions mentioned above being mono- or bicyclic aromatic), phenylthio, phenylsulfinyl, phenylsulfonyl, and for which R′b and R′c represent hydrogen, alkyl or cycloalkyl, or alternatively R°3 represents a radical —C≡C-Rd for which Rd is alkyl, phenyl, phenylalkyl, phenoxyalkyl, phenylthioalkyl, N-alkyl-N-phenylaminoalkyl, mono- or bicyclic aromatic heterocyclyl, heterocyclylalkyl, heterocyclyloxyalkyl, heterocyclylthioalkyl, heterocyclylaminoalkyl, N-alkyl-N-heterocyclylaminoalkyl, (the heterocyclyl portions mentioned above being mono- or bicyclic aromatic), or alternatively R°3 represents a —CF2-phenyl or mono- or bicyclic aromatic —CF2-heterocyclyl radical,

[0015] Y represents a radical >CH—Re for which Re is hydrogen, fluoro, hydroxyl, alkyloxy, cycloalkyloxy,-carboxyl, alkyloxycarbonyl, cycloalkyloxycarbonyl, —NRaRb or —CO—NRaRb for which Ra and Rb are defined as above for R2 or one represents a hydrogen atom and the other represents an alkyloxycarbonyl, acyl, cycloalkylcarbonyl, benzoyl or heterocyclylcarbonyl radical in which the heterocyclyl portion is mono- or bicyclic aromatic, or alternatively Y represents a difluoromethylene, carbonyl, hydroxyiminomethylene, alkyloxyiminomethylene or cycloalkyloxyiminomethylene radical or a 1,1-cycloalkylene radical containing 3 to 6 carbon atoms; and

[0016] n is an integer from 0 to 4;

[0017] it being understood that the phenyl, benzyl, benzoyl or heterocyclyl radicals or portions mentioned above may optionally be substituted on the ring with 1 to 4 substituents chosen from halogen, hydroxyl, alkyl, alkyloxy, alkyloxyalkyl, haloalkyl, trifluoromethyl, trifluoromethoxy, trifluoromethylthio, carboxyl, alkyloxycarbonyl, cyano, alkylamino, —NRaRb for which Ra and Rb are defined as above, phenyl, hydroxyalkyl, alkylthioalkyl, alkylsulfinylalkyl and alkylsulfonylalkyl,

[0018] in their enantiomeric or diastereoisomeric forms or mixtures of these forms, and/or, where appropriate, in their syn or anti form or a mixture thereof, as well as the salts thereof, are powerful antibacterial agents.

[0019] It is understood that the alkyl or acyl radicals and portions contain (except where especially mentioned) 1 to 10 carbon atoms in a straight or branched chain and that the cycloalkyl radicals contain 3 to 6 carbon atoms.

[0020] It is also understood that the radicals which represent or bear a halogen atom represent a halogen chosen from fluorine, chlorine, bromine and iodine, wherein fluorine is an embodiment of particular interest.

[0021] In the above general formula, when the radicals represent or bear a mono- or bicyclic aromatic heterocyclyl substituent, this substituent contains 5 to 10 chain members and may be chosen (in a nonlimiting manner) from thienyl, furyl, pyrrolyl, imidazolyl, thiazolyl, oxazolyl, thiadiazolyl, oxadiazolyl, tetrazolyl, pyridyl, pyridazinyl, pyrazinyl, pyrimidinyl, indolyl, benzothienyl, benzofuryl indazolyl, benzothiazolyl, naphthyridinyl, quinolyl, isoquinolyl, cinnolyl, quinazolyl, quinoxalyl, benzoxazolyl and benzimidazolyl which may optionally be substituted with the substituents listed above.

[0022] According to the invention, the products of general formula (I) may be obtained by coupling the chain R3 with the heterocyclylalkylpiperidine derivative of general formula:

[0023] in which X1, X2, X3, X4, X5, R1, R2, Y and n are defined as above, and R2 is protected when it bears a carboxyl or amino radical, optionally followed by removal of the acid-protecting or amine-protecting radical, optional separation of the enantiomeric or diastereoisomeric forms and/or, where appropriate, of the syn or anti forms and optional conversion of the product obtained into a salt.

[0024] The coupling of the chain R3 with the piperidine is advantageously carried out by the action of a derivative of general formula (IIa):

R3—X (IIa)

[0025] in which R3 is defined as above and X represents a halogen atom, a methylsulfonyl radical, a trifluoromethylsulfonyl radical or a p-toluenesulfonyl radical, working in anhydrous medium, which is optionally inert (for example nitrogen or argon) in an organic solvent such as an amide (for example dimethylformamide), a ketone (for example acetone) or a nitrile (for example acetonitrile) in the presence of a base such as an organonitrogen base (for example triethylamine) or a mineral base (alkaline carbonate, for example potassium carbonate) at a temperature of between 20° C. and the reflux temperature of the solvent. It is understood that the nitrogen atom of the piperidine in the derivative of general formula (II) is optionally protected according to the usual methods which do not affect the rest of the molecule or the reaction; for example, the protection is carried out by a protecting radical chosen from t-butoxycarbonyl and benzyloxycarbonyl.

[0026] In one embodiment of the invention, a derivative of general formula (IIa) for which X is a bromine or iodine atom is reacted.

[0027] When R3 is a phenyl radical, it is also possible to act on the iodo or bromo derivative R3—X in the presence of a palladium catalyst according to the method described in J. Org. Chem., 6066 (1997) or Tet. Lett., 6359 (1997). The palladium catalyst may be chosen from tris(dibenzylideneacetone)dipalladium, and palladium diacetate with a ligand such as 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl or 2-(di-t-butylphosphino)biphenyl, for example, a base such as sodium tert-butoxide or cesium carbonate in a solvent such as tetrahydrofuran, tetraglyme or toluene, optionally in the presence of a crown ether such as 18-C-6 (1,4,7,10,13,16-hexaoxacyclooctadecane). The reaction is carried out at a temperature of between 20° C. and 110° C.

[0028] When R3 represents a radical -alk-R°3 for which alk is an alkyl radical and R°3 represents —C≡C-Rd in which Rd is phenyl, phenylalkyl, heterocyclyl or mono- or bicyclic aromatic heterocyclylalkyl, optionally one may couple an alkynyl halide: HC≡C-alk-X for which alk is defined as above and X is a halogen atom, and then may substitute the chain with a phenyl, phenylalkyl, heterocyclyl or heterocyclylalkyl radical.

[0029] In this alternative, the addition of the alkynyl chain is carried out using an alkynyl halide HC≡C-alk-X for which X is optionally a bromine atom, under the conditions listed above for the coupling of the chain R3, in the presence or absence of an alkali metal iodide such as, for example, potassium iodide or sodium iodide.

[0030] The substitution with a phenyl or heterocyclyl radical is carried out by the action of a halide derived from the cyclic radical to be substituted, in the presence of triethylamine, in anhydrous medium in a solvent such as an amide (for example dimethylformamide) or a nitrile (for example acetonitrile) and in the presence of a palladium salt such as, for example, tetrakis(triphenylphosphine)palladium and cuprous iodide, at a temperature of between 20° C. and the reflux temperature of the solvent.

[0031] The substitution with a phenylalkyl or heterocyclylalkyl radical is carried out by the action of the corresponding halide, in basic medium, for example in the presence of potassium hydride or sodium hydride or n-butyllithium, in a solvent such as an ether (tetrahydrofuran) or an amide (dimethylformamide) at a temperature of between −60° C. and the boiling point of the reaction medium.

[0032] It is understood that, if the alkyl radicals represented by R3 bear carboxyl or amino substituents, these substituents are protected beforehand then freed after the reaction. The process is performed according to the usual methods which do not affect the rest of the molecule, in particular according to the methods described by T. W. Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis (2nd edition), A. Wiley—Interscience Publication (1991), or by McOmie, Protective Groups in Organic Chemistry, Plenum Press (1973).

[0033] The protected carboxyl radical borne by R2 may be chosen from readily hydrolyzable esters. Examples are the methyl, benzyl, and tert-butyl esters, or the phenyl propyl or allyl esters. The protection of the carboxyl radical is optionally carried out at the same time as the reaction.

[0034] Where appropriate, the amino radical is protected using the usual protecting radicals mentioned in the above references.

[0035] These protecting radicals are installed and removed according to the usual methods, mentioned above for R3.

[0036] When R3 represents a radical-alk-R°3 for which alk is an alkyl radical and R°3 represents a phenoxy, phenylthio, phenylamino, heterocyclyloxy, heterocyclylthio or heterocyclylamino radical in which the heterocyclyl portion is aromatic, optionally the chain may be constructed step by step, by first condensing a chain HO-alk-X, for which X is a halogen atom (optionally iodine), under the conditions described above for the reaction of the product of general formula (IIa), and then by converting the hydroxyalkyl chain into a haloalkyl, methanesulfonylalkyl or p-toluenesulfonyl-alkyl chain, and finally by reacting, in basic medium, an aromatic derivative of structure Ar—ZH for which AR is an aromatic phenyl or heterocyclyl radical and Z is a sulfur, oxygen or nitrogen atom.

[0037] The conversion of the hydroxylated chain into a haloalkyl or p-toluenesulfonyl chain is carried out according to the usual methods of halogenation or sulfonylation, especially by reacting a halogenating agent, for instance, thionyl chloride, halophosphorus derivatives: for example phosphorus trichloride or tribromide or a sulfonylating agent such as, for example, methanesulfonyl chloride, p-toluenesulfonyl chloride or trifluoromethanesulfonic anhydride. The reaction is carried out in an organic solvent, for instance a chlorinated solvent (for example dichloromethane or chloroform), at a temperature of between 0° C. and 60° C. In certain cases, it may be advantageous to work in the presence of a base, for instance pyridine or triethylamine.

[0038] The reaction of the aromatic derivative Ar—ZH is advantageously carried out as described above for the action of the derivative of general formula (IIa), in the presence of a base, for example such as a nitrogenous base, in an organic solvent such as an amide (for example dimethylformamide), a ketone (for example acetone) or a nitrile (for example acetonitrile), in the presence of a base such as a nitrogenous organic base (for example triethylamine) or a mineral base (alkali metal carbonate: for example potassium carbonate) at a temperature of between 20° C. and the reflux temperature of the reaction mixture. It may be advantageous to work in the presence of potassium iodide.

[0039] According to the invention, the heterocyclyl-alkylpiperidine derivatives of general formula (II) may be prepared according to the coupling method described below, and then where appropriate converted according to one of the methods {circle over (1)} to {circle over (9)} below, via a subsequent operation starting with one of the derivatives of general formula (II) already obtained, to prepare the derivatives corresponding to the various alternatives of Y and/or of R1, R′1, R′2, R′3, R′4 or R′5.

[0040] It is understood that when carboxylic acid radicals are present on the molecule, these radicals are protected beforehand and then freed after the reaction according to the usual methods which do not affect the rest of the molecule, especially according to the methods mentioned in the references cited above. It is also understood that, prior to the reactions which may interfere with the amine of the piperidine in the derivative of general formula (II), this amine is protected, and then freed after the reaction. The protection is carried out according to the usual methods, as specified above, especially via a t-butoxycarbonyl or benzyloxycarbonyl radical.

[0041] According to the invention, the preparation of the products of general formula (II) for which Re in Y is a hydrogen atom is carried out by coupling a heterocyclic derivative of general formula:

[0042] in which R1, X1, X2, X3, X4 and X5 are defined as above and Hal represents a halogen atom, with a piperidine derivative of general formula:

[0043] in which Rz is a protecting radical and R″2 is defined as above or represents a protected radical if R2 represents or bears a carboxylic acid function, followed by removal of the protecting radicals and/or followed by conversion, via a subsequent operation, of the substituents of the bicycle of the heterocyclylalkylpiperidine derivative of general formula (II) thus obtained, to give the expected derivative bearing the radical R1, R′1, R′2, R′3, R′4, or R′5, and, where appropriate, removal of the protecting radical(s) still present on the molecule.

[0044] The radical Rz may be any protecting group for the nitrogen atom which is compatible with the reaction (for example t-butyloxycarbonyl or benzyloxycarbonyl). The protecting groups for the acid functions are chosen from the usual groups whose installation and removal do not affect the rest of the molecule, especially those mentioned in the references cited above.

[0045] The reaction is carried out by the successive action of an organoborane (for example 9-borabicyclo-[3.3.1]nonane) in a solvent such as an ether (for example tetrahydrofuran or dioxane) at a temperature of between −20° C. and 20° C., and then of the bicyclic derivative of general formula (III) wherein Hal optionally represents a bromine or iodine atom or a chlorine atom, by analogy with the methods described by Suzuki et al., Pure and Appl. Chem., 57, 1749 (1985). The reaction is generally carried out in the presence of a palladium salt (for example diphenylphosphinoferrocenepalladium chloride) and of a base such as potassium phosphate, at a temperature of between 20° C. and the reflux temperature of the solvent.

[0046] {circle over (1)} The heterocyclylalkylpiperidines of general formula (II) for which Re in Y represents a hydroxyl radical may be prepared by oxidation in basic medium of the corresponding heterocyclylalkylpiperidine derivative of general formula (II) for which Re in Y is a hydrogen atom. The oxidation is carried out by the action of oxygen, optionally in an inert solvent such as dimethyl sulfoxide in the presence of tert-butanol and of a base such as potassium tert-butoxide or sodium tert-butoxide at a temperature of between 0° C. and 100° C.

[0047] The heterocyclylalkylpiperidine derivative for which Re in Y is a fluorine atom is prepared by fluorination starting with a derivative for which Re is hydroxyl. The reaction is carried out in the presence of a sulfur fluoride [for example in the presence of an aminosulfur trifluoride (diethylaminosulfur trifluoride (Tetrahedron, 44, 2875 (1988), bis(2-methoxyethyl)aminosulfur trifluoride (Deoxofluor®), or morpholinosulfur trifluoride, for example) or alternatively in the presence of sulfur tetrafluoride (J. Org. Chem., 40, 3808 (1975); alternatively, the fluorination reaction can also be carried out using a fluorinating agent such as hexafluoropropyldiethylamine (JP 2 039 546) or N-(2-chloro-1,1,2-trifluoroethyl)diethylamine.

[0048] The process is performed in an organic solvent such as a chlorinated solvent (for example dichloromethane, dichloroethane or chloroform), or in an ether (for example tetrahydrofuran or dioxane), at a temperature of between −78° C. and 40° C., or optionally between 0° C. and 30° C. It is advantageous to work in inert medium (especially argon or nitrogen).

[0049] The heterocyclylalkylpiperidine derivative of general formula (II) for which Re in Y is an alkyloxy or cycloalkyloxy radical is prepared by the action of an alkyl or cycloalkyl halide on the corresponding derivative of general formula (II) for which Re is hydroxyl. The reaction is generally carried out using the bromide or chloride, in an inert solvent such as N,N-dimethylformamide or dimethyl sulfoxide, in the presence of an acid acceptor such as a trialkylamine (for example triethylamine) or an alkali metal hydride (for example sodium hydride), at a temperature of between 20° C. and 100° C.

[0050] The heterocyclylalkylpiperidine derivative of general formula (II) for which Y is a carbonyl radical may be prepared by oxidation of the corresponding derivative of general formula (II) for which Re in Y is a hydroxyl radical. This oxidation is carried out, for example, using potassium permanganate optionally in a solution of sodium hydroxide (for example 3N sodium hydroxide), at a temperature of between −20° C. and 20° C., or alternatively by the action of oxalyl chloride in the presence of dimethyl sulfoxide, followed by the addition of an amine such as triethylamine, in an inert solvent such as dichloromethane or dimethyl sulfoxide, at a temperature of between −60° C. and 20° C., by analogy with the method described by D. Swern et al., J. Org. Chem., 44, 4148 (1979).

[0051] The heterocyclylalkylpiperidine derivative of general formula (II) for which Y is a difluoromethylene radical may be prepared by dihalogenation of the product of general formula (II) for which Y is carbonyl, under conditions analogous to those of the fluorination described above.

[0052] The heterocyclylalkylpiperidine derivative of general formula (II) for which Y is a hydroxyiminomethylene radical may be prepared by the action of hydroxylamine on a derivative of general formula (II) for which Y is a carbonyl radical. The reaction is generally carried out in an inert solvent such as an alcohol (methanol or ethanol) and optionally in the presence of sodium hydroxide (for example 1N sodium hydroxide), at a temperature of between 0° C. and the boiling point of the reaction mixture.

[0053] The heterocyclylalkylpiperidine derivative of general formula (II) for which Y is an alkyloxyiminomethylene or cycloalkyloxyiminomethylene radical may be prepared by the action of an alkyl or cycloalkyl halide on the corresponding derivative of general formula (II) for which Y is hydroxyiminomethylene. The reaction is generally carried out in an inert solvent such as N,N-dimethylformamide or dimethyl sulfoxide, in the presence of an acid acceptor such as a trialkylamine (for example triethylamine) or an alkali metal hydride (for example sodium hydride), at a temperature of between 20° C. and 100° C. A bromide is one example of interest in the present invention.

[0054] The heterocyclylalkylpiperidine derivative of general formula (II) for which Re in Y is a radical —NRaRb may be prepared from the corresponding tosyloxy derivative by the action of an amine HNRaRb (or, where appropriate, of ammonia when Re is —NH2) in an inert solvent such as N,N-dimethylformamide or dimethyl sulfoxide, at a temperature of between 20° C. and the boiling point of the reaction mixture. When ammonia is reacted, the process is optionally performed under pressure (2 to 20 atmospheres) at a temperature of between 20° C. and 100° C. When the process is performed using an amine HNRaRb, the reaction is optionally carried out in the presence of a base such as a trialkylamine (for example triethylamine), pyridine or an alkali metal hydride (for example sodium hydride).

[0055] The derivative for which Re in Y is tosyloxy is obtained from the product of general formula (II) for which Re in Y is hydroxyl, by the action of tosyl chloride in pyridine, at a temperature of between −10° C. and 20° C.

[0056] The heterocyclylalkylpiperidine derivative of general formula (II) for which Re in Y is a carboxyl radical may be prepared by the action of an alkaline cyanide on the corresponding tosyloxy derivative, in an organic solvent such as dimethylformamide or dimethyl sulfoxide or in aqueous-organic medium, for example a water-alcohol mixture, at a temperature of between 0° C. and the boiling point of the reaction mixture, followed by hydrolysis of the nitrile obtained by the action of a strong acid such as hydrochloric acid, and optionally of a lower aliphatic alcohol, at a temperature of between 0° C. and the boiling point of the reaction mixture. Sodium cyanide or potassium cyanide are both options according to the present invention.

[0057] The heterocyclylalkylpiperidine derivative of general formula (II) for which Re in Y is an alkyloxycarbonyl or cycloalkyloxycarbonyl or —CO—NRaRb radical may be prepared by the action, respectively, of the alcohol or of the corresponding amine on the derivative of general formula (II) for which Re in Y is a carboxyl radical. The reaction is carried out in the presence of a coupling agent such as a carbodiimide (for example N,N′-dicyclohexylcarbodiimide) or N,N′-carbonyldiimidazole, in an inert solvent such as an ether. (for example tetrahydrofuran or dioxane), an amide (N,N-dimethylformamide), a chlorinated solvent (for example methylene chloride, 1,2-dichloroethane or chloroform) or dimethyl sulfoxide, at a temperature of between 0° C. and the reflux temperature of the reaction mixture.

[0058] {circle over (2)} The heterocyclylalkylpiperidine derivative of general formula (II) for which Y is a 1,1-cycloalkylene radical may be prepared by the action, in basic medium, of a product of structure Hal-Alk-Hal for which Alk is an alkylene radical corresponding to the expected cycloalkylene, on a heterocyclylalkylpiperidine derivative for which Re in Y is a hydrogen atom. The reaction is generally carried out in an inert solvent such as N,N-dimethylformamide or dimethyl sulfoxide, in the presence of an acid acceptor such as an alkali metal hydride (for example sodium hydride), at a temperature of between 20° C. and 100° C.

Diederich and P. J. Stang, Metal Catalysed Cross-coupling Reactions, Wiley-VCH, (1997) in the presence of a palladium salt (for example tetrakis(triphenylphosphine) or diphenylphosphinoferrocenepalladium chloride) and of a base such as potassium phosphate, in an inert solvent such as an amide (for example N,N-dimethylformamide), an ether (for example tetrahydrofuran) or a nitrile (for example acetonitrile), at a temperature of between 20° C. and the reflux temperature of the reaction mixture.

[0060] {circle over (4)} The heterocyclylalkylpiperidine derivatives of general formula (II) for which one from among R1, R′1, R′2, R′3, R′4 and R′5 represents a radical —NRaRb may be prepared by the action of an amine HNRaRb on a derivative of general formula (II) for which the substituent R′i (R′i meaning one of the substituents R1, R′1, R′2, R′3, R′4 or R′5) is a bromine, iodine or chlorine atom, by analogy with the methods described in J.

Org. Chem., 57, 671 (1992) optionally followed by hydrolysis of the ester obtained. The reaction is carried out in particular by the successive action of an amide (for example lithium diisopropylamide) followed by a methyl halide (for example methyl iodide) or a derivative of formula Hal-Alk-Hal (Hal in one embodiment being a bromine atom) in a polar solvent (for example hexamethylphosphorotriamide) at a temperature of between 0° C. and 60° C.

[0109] It is understood that the processes listed above for the preparation of the piperidine derivatives of general formula (IV) may also be applied to the derivatives of general formula (II) if optionally first one couples the piperidine with the heterocyclic derivative of general formula (III) and then converts the radical R2 under the conditions described above.

[0110] It is also understood that the methods described below in the examples also form part of the present invention.

[0111] It is understood that the derivatives of general formulae (I) and (II) may exist in enantiomeric or diastereoisomeric forms or in syn or anti form. The enantiomeric or diastereoisomeric and syn or anti forms and the mixtures thereof also fall within the context of the present invention. These forms may be separated according to the usual methods, especially by chromatography on silica or by high performance liquid chromatography (HPLC).

[0112] The heterocyclylalkylpiperidine derivatives of general formula (I) may be purified, where appropriate, by physical methods such as crystallization or chromatography.

[0113] The heterocyclylalkylpiperidine derivatives of general formula (I) may, where appropriate, be converted into addition salts with acids, by the known methods. It is understood that these salts also fall within the context of the present invention.

[0114] As examples of addition salts with pharmaceutically acceptable acids, mention may be made of the salts formed with mineral acids (hydrochlorides, hydrobromides, sulfates, nitrates and phosphates) or with organic acids (succinates, fumarates, tartrates, acetates, propionates, maleates, citrates, methanesulfonates, ethanesulfonates, phenylsulfonates, p-toluenesulfonates, isethionates, naphthylsulfonates or camphorsulfonates, or with substitution derivatives of these compounds).

[0115] Some of the heterocyclylalkylpiperidine derivatives of general formula (I) bearing a carboxyl radical may be converted into metal salts or into addition salts with nitrogen bases according to the methods that are known per se. These salts also fall within the context of the present invention. The salts may be obtained by the action of a metallic base (for example an alkali metal or alkaline-earth metal), ammonia or an amine, on a product according to the invention, in a suitable solvent such as an alcohol, an ether or water, or by exchange reaction with a salt of an organic acid. The salt formed precipitates after optional concentration of the solution, and is separated out by filtration, settling or freeze-drying.

[0116] Examples of pharmaceutically acceptable salts which may be mentioned are the salts with alkali metals (sodium, potassium or lithium) or with alkaline-earth metals (magnesium or calcium), the ammonium salts or the salts of nitrogen bases (ethanolamine, diethanolamine, trimethylamine, triethylamine, methylamine, propylamine, diisopropylamine, N-N-dimethylethanolamine, benzylamine, dicyclohexylamine, N-benzyl-β-phenethylamine, N,N′-dibenzylethylenediamine, diphenylenediamine, benzhydrylamine, quinine, choline, arginine, lysine, leucine or dibenzylamine).

[0117] The heterocyclylalkylpiperidine derivatives according to the invention are particularly advantageous antibacterial agents.

[0118] In vitro, the heterocyclylalkylpiperidine derivatives according to the invention have been found to be active on gram-positive microorganisms at concentrations of between 0.03 μg/ml and 4 μg/ml on meticillin-resistant Staphylococcus aureus AS5155, and also, for most of them, at concentrations of between 0.03 μg/ml and 8 μg/ml on Streptococcus pneumoniae 6254-01; they have also been found to be active on gram-negative microorganisms such as, for example, and in a nonlimiting manner, on Moraxella catarrhalis IPA 152, at concentrations of between 0.12 μg/ml and 64 μg/ml. In vivo, they have been found to be active on experimental infections of mice with Staphylococcus aureus IP8203, either subcutaneously at doses of between 18 mg/kg and 150 mg/kg (DC50), or orally at doses of between 20 mg/kg and 150 mg/kg.

[0119] Finally, the products according to the invention are particularly advantageous on account of their low toxicity. None of the products has shown any toxicity subcutaneously at the dose of 100 mg/kg in mice (two administrations).

[0120] In the general formula (I), the products for which

[0121] X1, X2, X3, X4 and X5 represent, respectively, >C—R′1 to >C—R′5, or alternatively not more than one of them represents a nitrogen atom,

[0122] R1, R′1, R′2, R′3, R′4 and R′5 are identical or different and represent a hydrogen or halogen atom or an alkyl or alkyloxy radical, or represent a methylene radical substituted with alkyloxy,

[0123] R2 represents carboxyl, alkyloxycarbonyl or —CONRaRb (for which Ra represents a hydrogen atom and Rb represents a hydrogen atom or a hydroxyl radical) or

[0124] R2 represents hydroxymethyl, alkyl containing 1 or 2 carbon atoms substituted with carboxyl or alkyloxy-carbonyl,

[0125] R3 represents a radical alk-R°3 for which alk is an alkyl radical and R°3 represents hydrogen, cycloalkyl, cycloalkylthio, phenyl, phenoxy, phenylthio, phenylamino, heterocyclyloxy or heterocyclylthio or alternatively R°3 represents —CR′b=CR′c-R′a for which R′a represents phenyl, and for which R′b and R′c represent hydrogen,

[0126] Y represents a radical >CH—Re for which Re is hydrogen, fluoro or hydroxyl,

[0127] n is an integer from 2 to 3,

[0128] it being understood that the phenyl or heterocyclyl radicals or portions mentioned above may be optionally substituted on the ring with 1 to 4 halogens.

[3887] The present invention also relates to pharmaceutical compositions containing at least one heterocyclylalkyl-piperidine derivative according to the invention, where appropriate in the form of a salt, in pure form, or in the form of a combination with one or more compatible and pharmaceutically acceptable diluents and/or adjuvants.

[3888] The compositions according to the invention may be used orally, parenterally, topically, rectally, or as aerosols.

[3889] Solid compositions for oral administration which were optionally used include tablets, pills, gel capsules, powders or granules. In these compositions, the active product according to the invention may optionally be mixed with one or more inert diluents or adjuvants, such as sucrose, lactose or starch. These compositions may comprise substances other than diluents, for example a lubricant such as magnesium stearate or a coating intended for controlled release.

[3890] Liquid compositions for oral administration which may be used include pharmaceutically acceptable solutions, suspensions, emulsions, syrups and elixirs containing inert diluents such as water or liquid paraffin. These compositions may also comprise substances other than diluents, for example wetting, sweetening or flavoring products.

[3891] The compositions for parenteral administration may be sterile solutions or emulsions. Solvents or vehicles which may be used include water, propylene glycol, a polyethylene glycol, plant oils, in particular olive oil, and injectable organic esters, for example ethyl oleate. These compositions may also contain adjuvants, in particular wetting agents, isotonic agents, emulsifiers, dispersants and stabilizers.

[3892] The sterilization may be carried out in several ways, for example using a bacteriological filter, by irradiation or by heating. The compositions may also be prepared in the form of sterile solid compositions which may be dissolved at the time of use in sterile water or any other injectable sterile medium.

[3893] The compositions for topical administration may be, for example, creams, ointments, lotions or aerosols.

[3894] The compositions for rectal administration were suppositories or rectal capsules which contain, besides the active principle, excipients such as cocoa butter, semi-synthetic glycerides or polyethylene glycols.

[3895] The compositions may also be aerosols. For use in the form of liquid aerosols, the compositions may be stable sterile solutions or solid compositions dissolved at the time of use in apyrogenic sterile water, in saline or any other pharmaceutically acceptable vehicle. For use in the form of dry aerosols intended to be inhaled directly, the active principle was finely divided and combined with a water-soluble solid diluent or vehicle with a particle size of from 30 to 80 μm, for example dextran, mannitol or lactose.

[3896] In human therapy, the novel heterocyclylalkyl-piperidine derivatives according to the invention were particularly useful in the treatment of infections of bacterial origin. The doses depend on the desired effect and on the duration of the treatment. The doctor will determine the dosage she or he considers most appropriate as a function of the treatment, depending on the age, weight, degree of infection and other factors specific to the individual to be treated. Generally, the doses were between 750 mg and 3 g of active product taken 2 or 3 times a day orally or between 400 mg and 1.2 g intravenously for an adult.
