An atom‐ and step‐economic access to an array of unprotected meta‐substituted primary anilines was disclosed using the Semmler–Wolff reaction, promoted by molecular iodine. Therein, noble metal catalysts and inert atmosphere are unnecessary while the forcing reaction conditions and the lengthy synthesis can be avoided. The synthetic utility of this approach is evident in the de novo syntheses of three
利用分子碘促进的Semmler-Wolff反应,揭示了一系列无保护的间位取代的一级苯胺的原子经济和阶梯经济性。其中,不需要贵金属催化剂和惰性气氛,同时可以避免强制反应条件和冗长的合成。这种方法的合成效用在三个具有良好总收率的生物活性分子的从头合成中很明显。
