structures are still very rare. In this paper, we report a mild, catalyst‐free and operationally simple strategy for the direct aminofluoroalkylation of olefins driven by the noncovalent interaction between N‐allylanilines and fluoroalkyl iodides. This photochemical transformation features synthetic simplicity, mild reaction conditions, without the use of any photoredox catalyst, and high functional group tolerance
氟化氮丙啶是非常重要的结构基序,但是接近这种结构的方法仍然很少。在本文中,我们报告了一种温和,无催化剂且操作简单的策略,该策略用于由N-烯丙胺和氟代烷基碘之间的非共价相互作用驱动的烯烃直接氨基氟代烷基化。这种光化学转化具有合成简单,反应条件温和,无需使用任何光氧化还原催化剂和高官能团耐受性的特点。此外,该结构可以用作合成β-氟烷基化烷基胺衍生物的重要前体,例如氟化氨基酸和氟化2-吡咯烷酮。
