Abstract: front page image
(EN)The present invention relates to substantially pure piperidine derivative compounds of formula (I) or (II) wherein R¿3? is -COOH or -COOR¿4?; R¿4? has 1 to 6 carbon atoms; A, B, and D are the substituents of their rings each of which may be different or the same, and are selected from the group consisting of hydrogen, halogens, alkyl, hydroxy, alkoxy, or other substituents. A process of preparing such piperidine derivative compounds in substantially pure form is also disclosed.
(FR)Dérivés de pipéridine sensiblement purs de formule (I) ou (II), dans lesquelles R¿3? est -COOH ou -COOR¿4?; R¿4? possède de 1 à 6 atomes de carbone, A, B et D sont les substituants de leurs cycles, chacun d'entre eux pouvant être différent ou identique, et sont choisis dans le groupe constitué d'hydrogène, d'halogène, d'alkyle, d'hydroxy, d'alcoxy ou d'autres substances.
