A new method for the oxidation of Hedione 1 to dehydrohedione 2, a high value intermediate in the flavour and fragrance industry, has developed based upon one pot α-chlorination-elimination sequence which can be readily scaled. The spontaneous elimination of the α-chloro in methanol was unprecedented and has allowed for the oxidation, typically performed in multiple steps/reactions, to be carried out
一种将 Hedione 1氧化成脱氢Hedione 2的新方法是香精香料工业中的一种高价值中间体,该方法基于一锅α-氯化-消除序列,可以很容易地扩展。α-氯在甲醇中的自发消除是前所未有的,并且允许氧化,通常在多个步骤/反应中进行,作为一锅法进行。使用硫酰氯进行反应的连续流动过程也已证明允许在反应过程中稳定、安全地释放 SO 2气体。
