With visible light irradiation of a catalytic amount of Ir(ppy) at room temperature, a number of N-aryl enamines were transformed into their corresponding indoline products in good to excellent yields without requiring any extra additives. This is the first example of the synthesis of indolines via the intramolecular cyclization of enamines under visible light irradiation.
在室温下用催化量的Ir(ppy)进行可见光照射时，许多N-芳基烯胺无需任何额外添加剂就能以良好至优异的产率转化为相应的二氢吲哚产物。这是在可见光照射下通过烯胺的分子内环化合成二氢吲哚的首例报道。
