5,6-Dihydroxy-N-methylmdole readily reacts with dehydroascorbic acid in aqueous solution at room temperature. The o-diphenol system of the indole derivative interacts with the α-diketone function of dehydroascorbic acid to form a 1,4-benzodioxane derivative. This type of reaction appears to be a general one since similar interactions occur between other o-diphenols and α-diketones. The mechanism by which the 1,4-benzodioxane derivative is obtained when adrenochrome is reduced with ascorbic acid is discussed.
5,6-二羟基-N-甲基吲哚在室温下与脱氢抗坏血酸在水溶液中迅速反应。吲哚衍生物的邻二酚系统与脱氢抗坏血酸的α-二酮功能相互作用,形成1,4-苯并二氧杂环己烷衍生物。这种类型的反应似乎是一种普遍的反应,因为类似的相互作用发生在其他邻二酚和α-二酮之间。讨论了当肾上腺素通过抗坏血酸还原时如何获得1,4-苯并二氧杂环己烷衍生物的机制。
