A novel and efficient iron(III)-catalyzed synthesis of multi-substituted imidazoles via [3+2] cycloaddition of nitroolefins and N-aryl benzamidines under the air atmosphere had been developed. This methodology is convenient, atom-economical, general, and eco-friendly in good yields and prefect regioselectivities.
多取代的咪唑的通过一种新颖的和有效的铁(III)催化的合成[3 + 2] nitroolefins和环加成Ñ的空气气氛下,芳基苯甲脒已经被开发出来。这种方法很方便,原子经济性,一般情况下,在良好的收益率和完善的区域选择性环保。
