An expedient large-scale synthesis of 3-perfluoroalkyl-7-azaindoles starting from 2-fluoropyridine is presented. The activation as 6-chloro-4-nitro derivative allows the further derivatization by nucleophilic aromatic substitution in the 4-position.
我们展示了一种从2-氟吡啶出发的便捷大规模合成3-全氟烷基-7-氮杂吲哚的方法。作为6-氯-4-硝基衍生物的活化使得在4位进行亲核芳香取代反应的进一步衍生化成为可能。
