and electron-rich arenes with β-nitroalkenes in HFIP was reported. The desired products are formed rapidly in excellent yields under mild conditions without the need for any additional catalysts or reagents. Further, this methodology can be applied to one-pot synthesis of biologically active tryptamine derivatives.
据报道,在 HFIP 中吲哚和富电子芳烃与 β-硝基烯烃发生有效且清洁的 FC 烷基化。在温和条件下以优异的产率快速形成所需产物,无需任何额外的催化剂或试剂。此外,该方法可应用于生物活性色胺衍生物的一锅合成。

for alkylation of N,N-dialkylanilines with substituted β-nitrostyrenes using 10 mol% of choline chloride-zinc chloride deep eutectic solvent at 70 °C. The reaction was highly regioselective and only para-substituted products have been prepared. Despite the sensitivity and weak reactivity of the aniline derivatives for the Friedel–Crafts reaction in acidic media, the presented procedure was successfully
