Herein we present a new strategy for the dehydrogenative–decarboxylative coupling of indoles with glyoxylic acid. A broad range of indoles were transformed into the corresponding 3-formylindoles in moderate to good yields and excellent functional group tolerance. Notably, no N-formylation product was detected under our conditions.
在这里,我们提出了
吲哚与
乙醛酸的脱氢-脱羧偶联的新策略。大量的
吲哚以中等至良好的产率和优异的官能团耐受性转化为相应的3-甲酰基
吲哚。值得注意的是,在我们的条件下没有检测到N-甲酰化产物。
