Title (EN) CHEMICAL PROCESS OF PREPARING DEHYDROHEDIONE
(FR) PROCÉDÉ CHIMIQUE DE PRÉPARATION DE DÉSHYDROHÉDIONE
Abstract:
(EN) Disclosed is a chemical process of preparing dehydrohedione from Hedione via α-chlorination and elimination steps. The process can be conducted in a one-pot process or in a continuous reactor system. Accordingly, a simple and cost effective process of preparing cis-Hedione enriched products is developed through reduction of dehydrohedione in the presence of a chiral catalyst system.
(FR) L'invention concerne un procédé chimique de préparation de déshydrohédione à partir d'hédione au moyen d'étapes d'α-chloration et d'élimination. Le procédé peut être mis en oeuvre dans un procédé monotope ou dans un système de réacteur continu. Par conséquent, un procédé simple et économique de préparation de produits enrichis en cis-hédione est développé par réduction de la déshydrohédione en présence d'un système de catalyseur chiral.
