Abstract:
1. A compound of formula (I): wherein: X represents oxygen or sulphur, R A represents CH B represents linear or branched (C or by a group of formula (III) in which groups: R or R D represents benzene substituted by wherein R and R′ are as defined hereinbefore, wherein: when A and B are in the ortho position in relation to one another on the benzene nucleus carrying them, B cannot represent linear or branched (C aryl is to be understood as phenyl, naphthyl, or biphenyl, which groups may be partially hydrogenated, heteroaryl is to be understood as any mono- or bi-cyclic aromatic group containing from 5 to 10 ring members, which may be partially hydrogenated on one of the rings in the case of bicyclic heteroaryls, and which contains from 1 to 3 hetero atoms selected from oxygen, nitrogen and sulphur, wherein the aryl and heteroaryl groups so defined may be substituted by from 1 to 3 groups selected from linear or branched (C 1 -C 6 )alkyl, linear or branched (C 1 -C 6 )alkoxy, carboxy, formyl, NR b R c (wherein R b and R c , which may be identical or different, each represents hydrogen, linear or branched (C 1 -C 6 )alkyl, aryl or heteroaryl), ester, amido, intro, cyano, O—C(Me) 2 COOR″ (wherein R″ is as defined hereinbefore), and halogen, its enantiomers and diastereoisomers, and addition salts thereof with a pharmaceutically-acceptable acid or base.
