Abstract

On prépare l'acide 6-oxo-2-méthyl-2,4-heptadiénoïque, et ses dérivés de formule générale I en faisant réagir un acétate d'énol de formule Il sur un agent d'halogénation dans l'eau ou dans un mélange d'eau et d'un solvant organique polaire, entre -20 degrés C et 50 degrés C, puis en faisant réagir le composé formé de formule III sur un déhalohydratant entre - 20 degrés C et +80 degrés C. Les composés ainsi obtenus sont des produits intermédiaires intéressants pour la synthèse de nombreux caroténoïdes.
