A copper-promoted reductive cross-coupling of nitroarenes with 4-alkyl-1,4-dihydropyridines for producing N-alkylbenzenamines is described. Using 4-alkyl-1,4-dihydropyridines as alkyl radical sources and internal reducing agents enables the construction of C(sp³)–N bonds under oxidative conditions, which provide an elegant complementary platform to assemble N-alkylbenzenamines with good tolerance for sensitive functional groups.

使用过氧化物驱动的自由基还原策略铜促进硝基芳烃与 4-烷基-1,4-二氢吡啶的交叉偶联

描述了一种铜促进的硝基芳烃与 4-烷基-1,4-二氢吡啶的还原交叉偶联，用于生产N-烷基苯胺。使用 4-烷基-1,4-二氢吡啶作为烷基自由基源和内部还原剂能够在氧化条件下构建 C(sp ³ )-N 键，这为组装N-烷基苯胺提供了一个优雅的互补平台，对敏感物质具有良好的耐受性官能团。
