The invention concerns products of formula (I), wherein: A represents H or -CH2-B in which B is selected from alkyl or (i) radicals, Z1 and Z2 represent H or form the radical (ii) in which Y1 and Y2, which may be identical or different, are selected from -O-, -S-, -N-, -NH-, -CH= or -CH2-, Y1 and Y2 forming a ring with the phenyl radical, Z represents -O- or -S-, X represents carboxy, tetrazolyl, -CO-NH-SO2-R6, R6 representing optionally substituted alkyl, alkenyl or phenyl, R represents, in particular, H, halogen, dioxol, carboxy, alkyl, phenylthioalkyl and phenylthio, which may be optionally substituted, R1, R2, R3, R4 and R5, which may be identical or different, represent in particular hydrogen, halogen, hydroxyl, alkyl, alkoxy, and R2 and R3 with the phenyl radical may likewise form the rings formed by Z1 and Z2, with the proviso that when A is H, Z1 and Z2 form (ii), products of formula (I) in all the isomeric forms, and the acid or base addition salts. |
