Process for the preparation of derivatives of 3,5-dihydroxy 6-oxo hexanoic acid having general formula (I) based on a dihydroxyacetal having general formula (II). In general formuli (I) and (II), R1 is an alkyl radical (1 to 4 carbon atoms), R is an alkyl radical (1 to 4 carbon atoms) or benzyl and P1 is a hydroxy function protective grouping. Procédé de préparation de dérivés de l'acide dihydroxy-3,5 oxo-6 hexanoïque de formule générale (I) à partir d'un dihydroxyacétal de formule générale (II). Dans les formules générales (I) et (II), R1 représente un radical alcoyle (1 à 4 atomes de carbone), R représente un radical alcoyle (1 à 4 atomes de carbone) ou benzyle et P1 représente un groupement protecteur de la fonction hydroxy.
