Patent ID: 7202255

Claim:
A compound selected from those of formula (I): wherein A, together with the carbon atoms to which it is bonded, represents a group of formula (a): wherein: W 1 , together with the carbon atoms to which it is bonded, represents phenyl or pyridyl, Z represents a group selected from hydrogen, halogen, linear or branched (C 1 –C 6 )alkyl, nitro, cyano, hydroxy, linear or branched (C 1 –C 6 )alkoxy, aryl, aryl-(C 1 –C 6 )alkyl in which the alkyl moiety is linear or branched, aryloxy, aryl-(C 1 -C 6 )alkoxy in which the alkoxy moiety is linear or branched and NR 5 R 6 wherein R 5 and R 6 , which may be identical or different, each represents a group selected from hydrogen and linear or branched (C 1 –C 6 )alkyl, R4 represents a group selected from hydrogen, linear or branched (C 1 –C 6 )alkyl, aryl and aryl-(C 1 –C 6 )alkyl in which the alkyl moiety is linear or branched or —C(O)—OR′ 5 wherein R′ 5 represents a group selected from linear or branched (C 1 –C 6 )alkyl, aryl and aryl-(C 1 –C 6 )alkyl in which the alkyl moiety is linear or branched, Y represents a group selected from oxygen or methylene, R 2 and R 3 form a bond, R 1 represents a group selected from hydrogen, linear or branched (C 1 –C 6 )alkyl, aryl, aryl-(C 1 –C 6 )alkyl in which the alkyl moiety is linear or branched or linear or branched (C 1 –C 6 )alkylene substituted by one or more identical or different groups selected from —OR″ 5 and —NR″ 5 R″ 6 wherein R″ 5 and R″ 6 have the same meaning as R 5 and R 6 defined hereinbefore, Z 1 and Z 2 , each represent hydrogen or, Z 1 and Z 2 , together with the carbon atoms to which they are bonded, form phenyl, it being understood that: when Z represents hydrogen, R 1 is other than hydrogen, and aryl may be a phenyl, naphthyl, dihydronaphthyl, tetrahydronaphthyl, indenyl or indanyl group, each of those groups being optionally substituted by one or more identical or different groups selected from halogen, linear or branched (C 1 –C 6 )alkyl, linear or branched (C 1 –C 6 )trihaloalkyl, hydroxy, linear or branched (C 1 –C 6 )alkoxy, and amino optionally substituted by one or two linear or branched (C 1 –C 6 )alkyl groups.
