Abstract
La présente invention est relative à un procédé de préparation de 17 alpha -hydroxy-21-acyloxy-progestérone, de formule I, dans laquelle R' représente un reste d'un acide carboxylique aliphatique ayant de 1 à 4 atomes de carbone, ou le radical benzoyle, caractérisé en ce que : a. On fait réagir un oomposé de formule Il dans laquelle R**2 représente un groupe protecteur facilement éliminable, avec un dialcoxyvinyllithium, afin d'obtenir un composé de formule III dans laquelle R**2 représente un groupe protecteur facilement éliminable et Alk représente un groupe alkye ayant de 1 à 4 atomes de carbone; b. On traite le composé obtenu par un acide minéral en solution alcoolique aqueuse, pour obtenir un composé de formule IV dans laquelle Alk a la signification indiquée pour la formule III; c. On réduit le composé obtenu en un composé de formule V dans laquelle Alk a la Signification indiquée pour la formule III; d. On convertit le composé obtenu en le mono- ou diacylate de formule VI dans laquelle Alk a la signification indiquée pour la formule III, R**1 la signification indiquée pour la formule I et R** 3 représente l'hydrogène ou a la signification de R**1 ; e. On oxyde le composé obtenu, selon le procédé d'Oppenauer, en un composé de formule VII dans laquelle Alk a la signification indiquée pour la formule III et R**1 la signification indiquée pour la formule I, et f. On oxyde le composé obtenu par un peracide carboxylique afin d'obtenir un composé formule I.
