Zusammenfassung:The present invention relates to an improved process for the preparation of Coenzyme Q. Coenzyme Q10 or CoQ10 has the chemical name 2-r(all-trans)-3, 7, 11, 15, 19, 23, 27, 31, 35, 39 - decamethyl - 2, 6, 10, 14, 18, 22, 26, 30, 34, 38 - tetracontadecaenyl] - 5, 6-dimethoxy -3- methyl -1,4-benzoquinone and has the formula (I). The invention also provides new intermediates useful for the preparation of CoQ10 and processes for their preparation. La présente invention concerne un processus amélioré pour la préparation du coenzyme Q. Le coenzyme Q10 ou CoQ10 présente le nom chimique 2-r(all-trans)-3, 7, 11, 15, 19, 23, 27, 31, 35, 39 - décaméthyl - 2, 6, 10, 14, 18, 22, 26, 30, 34, 38 - tétracontadécaényl] - 5, 6-diméthoxy -3- méthyl -1,4-benzoquinone et possède la formule (I). Cette invention a, aussi, pour objet de nouveaux intermédiaires utilisés dans la préparation de CoQ10 et des processus destinés à leur préparation.
