Title (EN) EPIMERIZATION BY STEREOSELECTIVE SYNTHESIS OF VITAMIN D ANALOGUES
(FR) ÉPIMÉRISATION PAR SYNTHÈSE STÉRÉOSÉLECTIVE D'ANALOGUES DE LA VITAMINE D
Abstract: front page image
(EN)A method for epimerization process of C-24 ketones to desired C-24 alcohol by stereo selective reduction using chiral borane reducing agents in the presence of chiral auxiliary such as (R)-2-methyl-CBS-oxazaborolidine for the preparation of calcipotriene intermediates and its process to calcipotriene.
(FR)L'invention concerne un procédé d'épimérisation de cétones C-24 vers l'alcool C-24 souhaité par réduction stéréosélective à l'aide d'agents réducteurs de borane chiral, en présence d'un auxiliaire chiral tel que (R)-2-méthyle-CBS-oxazaborolidine, pour la préparation d'intermédiaires du calcipotriène et leur traitement pour obtenir du calcipotriène.
