and dyes. Nitration methods for anilines under mild conditions are highly desired. Herein, we report a photochemical method for the nitration of anilines bearing various protecting groups by 5-methyl-1,4-dinitroimidazole as a new type of nitro source. This method is light-controlled and proceeds under mild reaction conditions with high efficiency. Fmoc-, Ts- and alkyl-protected anilines are all well
硝基苯胺是药物、材料和
染料中的重要组成部分。非常需要在温和条件下对
苯胺进行硝化的方法。在此,我们报道了一种以 5-甲基-
1,4-二硝基咪唑作为新型硝基源硝化带有各种保护基的
苯胺的光
化学方法。该方法是光控的,在温和的反应条件下进行,效率高。Fmoc-、Ts- 和烷基保护的
苯胺都被很好地硝化,具有良好的官能团耐受性。
