natural products, pharmaceuticals, and agrochemicals. Herein, we report the first B-alkyl Suzuki cross-coupling of 2-pyridyl ammonium salts to access functionalized 2-alkylpyridines. The use of well-defined, operationally simple Pd-NHCs permits for an exceptionally broad scope of the challenging B-alkyl C–N cross-coupling with organoboranes containing β-hydrogen, representing a novel method for the discovery
2-烷基吡啶是整个有机合成领域的一种特殊支架,在天然产物、药物和农用化学品中发挥着关键作用。在此,我们报道了 2-吡啶基铵盐的第一个 B-烷基 Suzuki 交叉偶联以获得功能化的 2-烷基吡啶。使用结构明确、操作简单的 Pd-NHC 可以实现极其广泛的具有挑战性的 B-烷基 C-N 与含有 β-氢的有机硼烷的交叉偶联,代表了一种发现备受追捧的分子的新方法用于植物保护。
