An electrocatalytic method has been developed to oxidize primary alcohols and aldehydes to the corresponding carboxylic acids using 4-acetamido-2,2,6,6-tetramethylpiperidin-1-oxyl (ACT) as a mediator. The method successfully converts benzylic, aliphatic, heterocyclic, and other heteroatom-containing substrates to the corresponding carboxylic acids in aqueous solution at room temperature. The mild conditions
已经开发出一种电催化方法,使用4-乙酰氨基-2,2,6,6-四甲基哌啶-1-氧基(ACT)作为介体,将伯醇和醛氧化为相应的羧酸。该方法在室温下将水溶液中的苄基,脂族,杂环和其他含杂原子的底物成功转化为相应的羧酸。温和的条件能够使立体化学保留在氧化位点附近,如左乙拉西坦(一种用于治疗癫痫的药物)的前体的40克规模合成所证明的。
