3-chloro-3-methyl-2-butanone in ethanolic KOH at room temperature gave 3,3-dimethyl-5-aryltetrahydro-2-furanone as a major product. The reaction can be tentatively explained by the combination of Favorskii rearrangement and aldol reaction.
芳香醛或杂芳香醛与 3-
氯-
3-甲基-2-丁酮在
乙醇 KOH 中在室温下反应得到 3,3-二甲基-5-芳基四氢-2-
呋喃酮作为主要产物。该反应可以用 Favorskii 重排和羟醛反应的结合来初步解释。
