A novel and direct approach to synthesize 1-aminoindole derivatives by Rh(iii)-catalyzed cyclization of 2-acetyl-1-arylhydrazines with diazo compounds via aryl C-H activation has been developed. This intermolecular annulation involving tandem C-H activation, cyclization and condensation steps proceeds efficiently in water, obviates the need of external oxidants, and displays a broad substituent scope
通过Rh(iii)与重氮化合物经芳基CH活化的Rh(iii)催化的2-乙酰基-1-芳基肼的环化反应合成1-氨基吲哚衍生物的新方法已经开发出来。这种涉及串联CH活化,环化和缩合步骤的分子间环化反应在水中有效地进行,消除了对外部氧化剂的需求,并显示出广泛的取代基范围。
