it is possible to activate toluene efficiently and use it directly for the benzylation of different 2-aminopyridines. The transformation is not restricted to simple toluene, but also substituted derivatives give the desired product in good yields. Effective cleavage of the pyridine moiety is presented.
甲苯作为常见 N-苄基化试剂(如苄基溴)的替代品,可以成为一种原子效率高的替代试剂。在镍催化和温和的氧化条件下,可以有效地活化甲苯并将其直接用于不同2-氨基吡啶的苄基化反应。转化不仅限于简单的甲苯,而且取代的衍生物也能以良好的产率得到所需的产物。给出了吡啶部分的有效裂解。
