Patent ID: 7326722

Claim:
A compound in the form of an enantiomer (1R,2R) or (1S,2S) or in the form of a threo diastereoisomer, corresponding to general formula (I) in which A represents a group of general formula N—R 1 , a group of general formula N + (O − )R 1 or a group of general formula N + (R′)R 1 , and in which R 1 represents either a hydrogen atom, or a linear or branched (C 1 –C 7 )alkyl group optionally substituted with one or more fluorine atoms, or a (C 4 –C 7 )cycloalkyl group, or a (C 3 –C 7 )cycloalkyl(C 1 –C 3 )alkyl group, or a phenyl(C 1 –C 3 )alkyl group optionally substituted with one or two hydroxyl or methoxy groups, or a (C 2 –C 4 )alkenyl group, or a (C 2 –C 4 )alkynyl group, R′ represents a linear or branched (C 1 –C 7 )alkyl group, X represents a hydrogen atom or one or more substituents chosen from halogen atoms and trifluoromethyl, linear or branched (C 1 –C 4 )alkyl and (C 1 –C 4 )alkoxy groups, R 2 represents either a hydrogen atom, or one or more substituents chosen from halogen atoms and trifluoromethyl, (C 1 –C 4 )alkyl or (C 1 –C 4 )alkoxy groups, or amino groups of general formula NR 3 R 4 in which R 3 and R 4 each represent, independently of each other, a hydrogen atom or a (C 1 –C 4 )alkyl group, or form with the nitrogen atom carrying them a pyrrolidine, piperidine or morpholine ring, or a phenyl group optionally substituted with an atom or a group as defined for the symbol X above, in the form of a free base or of an addition salt with an acid.
