Abstract

Procédé de préparation de dérivés de l'azétidinone de l'une des formules Ia et Ib, qui consiste à traiter par un acide un mélange d'isomères cis et trans de 1a formule IV, à réduire le composé de la formule III obtenu et à éliminer le groupe protecteur R du mélange de diastéréomères de la formule II.Process for the preparation of azetidinone derivatives of one of the formulas Ia and Ib, which consists in treating with an acid a mixture of cis and trans isomers of the formula IV, in reducing the compound of formula III obtained and in removing the protective group R from the mixture of diastereomers of formula II.
