<p>[(Oxo-3-cyclohexyl)-4 phenyl]-2 propionic acid and its derivatives are prepared by converting (ethylenedioxo-3,3 cyclohexyl)-4 acetophenone or its derivatives, of general formula (IV) in which A denotes a group (a), B denotes a group (b), and R?1, R2, R3, R4, R5¿, which may be identical or different, each denote hydrogen or an alkyl group, to a desired compound of general formula (I), in which A4 denotes a group (c). This process is easier to implement on an industrial scale and produces a higher yield than prior art processes for preparing compounds of formula (I).</p> |
