of 2-alkylated pyridines by the nickel-catalyzed cross-coupling of two different electrophiles, 2-chloropyridines with alkyl bromides, is described. Compared to our previously published conditions for aryl halides, this method uses the different, more rigid bathophenanthroline ligand and is conducted at high concentration in DMF solvent. The method displays promising functional group compatibility and
描述了通过镍催化的两种不同亲电子试剂(2-氯吡啶与烷基溴)的交叉偶联合成 2-烷基化吡啶。与我们之前公布的芳基卤化物条件相比,该方法使用不同的、更刚性的红菲咯啉配体,并在 DMF 溶剂中以高浓度进行。该方法显示出有希望的官能团兼容性,并且条件与 Stille 耦合正交。
