A highly efficient one‐pot synthesis of polysubstituted pyridine has been achieved through copper‐catalyzed oxidative sp3 C−H coupling of acetophenones with toluene derivatives. Besides, the polysubstituted benzene was obtained through copper‐catalyzed coupling of acetophenones. Both of the reactions exhibited a good functional group tolerance to produce a 2,4,6‐triphenylpyridine or 1,3,5‐triarylbenzene
通过苯乙酮与甲苯衍生物的铜催化氧化sp 3 C-H偶联,已经实现了多取代吡啶的高效单锅合成。此外,多取代苯是通过铜催化的苯乙酮偶联制得的。这两个反应均显示出良好的官能团耐受性,可以高产率生产2,4,6-三苯基吡啶或1,3,5-三芳基苯。与以前的方法相比,这些转化可以高度灵活,高效地制备取代的吡啶和苯。
