yield of 2-[2,2-bis(indol-3-yl)ethyl]anilines and 3-(indolin-2-yl)indoles. Oligomerization of substituted indoles and N-methylindoles was investigated in the presence of catalytic amounts of scandium triflate in dichloromethane. Two types of indole oligomer, 2-[2,2-bis(indol-3-yl)ethyl]anilines and 3-(indolin-2-yl)indoles were obtained based on the substituent on indole ring. This study constitutes the
摘要 在二氯甲烷中催化量的三氟甲磺酸scan存在下,研究了取代的吲哚和N-甲基吲哚的低聚。基于吲哚环上的取代基,获得了两种类型的吲哚低聚物,即2- [2,2-双(吲哚-3-基)乙基]苯胺和3-(吲哚-2-基)吲哚。该研究构成了Sc(OTf)3催化的吲哚低聚的第一个实例,并获得了2- [2,2-双(吲哚-3-基)乙基]苯胺和3-(吲哚-2-基)苯胺的良好收率。吲哚。 在二氯甲烷中催化量的三氟甲磺酸scan存在下,研究了取代的吲哚和N-甲基吲哚的低聚。基于吲哚环上的取代基,获得了两种类型的吲哚低聚物,即2- [2,2-双(吲哚-3-基)乙基]苯胺和3-(吲哚-2-基)吲哚。该研究构成了Sc(OTf)3催化的吲哚低聚的第一个实例,并获得了2- [2,2-双(吲哚-3-基)乙基]苯胺和3-(吲哚-2-基)苯胺的良好收率。吲哚。
