A direct metal-free method for the synthesis of perfluoroalkylated indolizines by means of DIPEA-promoted tandem CN/CC bond formation was developed. Various substituted pyridines and bromoacetyl derivatives with methyl perfluoroalk-2-ynoates proceeded smoothly in this mild transformation, and the desired products were obtained in good to excellent yields under air.
开发了一种直接无金属的方法,该方法通过DIPEA促进的串联C N / C C键的形成来合成全氟烷基化的吲哚嗪。在这种温和的转化过程中,各种被全氟烷基-2-丙酮酸甲酯取代的吡啶和溴代乙酰基衍生物可顺利进行,并在空气中以良好或优异的收率获得所需的产物。
