The alkylation of aryl sulfamates and carbamates using iron catalysis is reported. The method constructs sp(2)-sp(3) carbon-carbon bonds and provides synthetically useful yields across a range of substrates (>35 examples). The directing group ability of sulfamates and carbamates, accompanied by their low reactivity toward conventional cross-couplings, renders these substrates useful for the synthesis of polyfunctionalized arenes.
本文报道了铁催化的芳基磺酰胺和氨基甲酸酯的烷基化反应。该方法构建了 sp(2)-sp(3) 碳-碳键,在一系列底物中提供了具有合成实用性的产率(>35 个实例)。磺酰胺和氨基甲酸酯的导向基团能力,以及它们对常规交叉偶联反应的低反应性,使得这些底物可用于多官能化芳基的合成。
