Abstract: front page image
(EN)Disclosed is a method for synthesizing sapropterin dihydrochloride. The present invention reduces a synthesis route of the sapropterin dihydrochloride, and resolves a racemate intermediate or an intermediage having a low antimer isomerism value by using a chiral resolving reagent, thereby obtaining an intermediate having a high antimer isomerism value. Raw materials are cheap and readily available, and the cost is significantly reduced, hence providing an effective scheme for mass industrial production of the sapropterin dihydrochloride.
(FR)L'invention concerne un procédé de synthèse de dichlorhydrate de saproptérine. La présente invention réduit une voie de synthèse du dichlorhydrate de saproptérine et sépare un intermédiaire racémate ou un intermédiaire ayant une faible valeur d'isomérisme d'antimère en utilisant un réactif de résolution chirale, ce qui permet d'obtenir un intermédiaire ayant une valeur élevée d'isomérisme d'antimère. Les matières premières sont peu coûteuses et facilement disponibles, et les coûts sont significativement réduits, ce qui permet d'obtenir un procédé efficace pour la production industrielle en masse du dichlorhydrate de saproptérine.
