An electrochemical monofluoroalkylation cyclization of -arylacrylamides to synthesize monofluorinated 2-oxindoles has been developed, which employs common dimethyl 2-fluoromalonate as a monofluoroalkyl radical precursor and obviates the use of prefunctionalized monofluoroalkylation reagents and sacrificial oxidants. A variety of monofluorinated nitrogen-containing heterocyclic compounds were efficiently obtained with satisfactory yields from readily available materials.
已开发出一种通过电化学将β-芳基丙烯酰胺进行单氟烷基化环化反应来合成单氟代2-氧化吲哚的方法，该方法使用常见的2-氟丙二酸二甲酯作为单氟烷基自由基前体，避免了使用预官能化的单氟烷基化试剂和牺牲性氧化剂。从容易获得的原料出发，以令人满意的产率高效地获得了多种含单氟的含氮杂环化合物。
