(EN) The present invention relates to compounds of formula (I) wherein (x) and (y) are single or double bonds; A is (1) or (2); R and R3 are hydrogen or acyl; R1 is hydrogen or fluorine; and wherein: when (y) is a single bond, R2 is hydrogen, fluorine methyl, trifluoromethyl; when (y) is a double bond, R2 is methylene provided that when one of (x) or (y) is a double bond the other is a single bond and at least one of R1 and R2 is fluorine or trifluoromethyl and the pharmaceutically acceptable salts thereof. The compounds of formula (I) are useful as aromatase inhibitors.(FR) La présente invention se rapporte à des composés de la formule (I) dans laquelle (x) et (y) représentent des liaisons simples ou doubles; A représente (1) ou (2); R et R3 représentent hydrogène ou acyle; R1 représente hydrogène ou fluor; et dans laquelle: lorsque (y) représente une liaison simple, R2 représente hydrogène, méthyle fluoré, trifluorométhyle; lorsque (y) représente une liaison double, R2 représente méthylène, à condition que, lorsque (x) ou (y) représente une liaison double, l'autre élément représente une liaison simple, et R1 et/ou R2 représente fluor ou trifluorométhyle. L'invention se rapporte également aux sels pharmaceutiquement acceptables de ces dérivés. Les composés de la formule (I) peuvent être utilisés comme inhibiteurs d'aromatase.
