Title (EN) PROCESS FOR PREPARING 5-[1-(4-CHLOROPHENYL)-METHYLENE]-1-HYDROXYMETHYL-2,2-DIMETHYL-CYCLOPENTANOL
(FR) PROCÉDÉ DE PRÉPARATION DU 5-[1-(4-CHLOROPHÉNYL)-MÉTHYLÈNE]-1-HYDROXYMÉTHYL-2,2-DIMÉTHYL-CYCLOPENTANOL
Abstract: front page image
(EN)A process for preparing diols (la) and (lb) with water and hydrogenating the resulting 5-[1 -(4-chlorophenyl)-meth-(E)-ylidene]-1 - hydroxymethyl-2,2-dimethyl-cyclopentanol (III) with hydrogen in the presence of a metal catalyst. Compounds (la), (lb) and (III) are intermediates for synthesizing Metconazole.
(FR)L'invention concerne un procédé de préparation de diols (1a) et (1b) avec de l'eau et d'hydrogénation du 5-[1-(4-chlorophényl)-méth-(E)-ylidène]-1-hydroxyméthyl-2,2-diméthyl-cyclopentanol (III) résultant par l'hydrogène, en présence d'un catalyseur métallique. Les composés (1a), (1b) et (III) sont des intermédiaires pour la synthèse du Metconazole.
