The addition of indoles to 4-methyl-2-trifluoromethyl-1,3-oxazin-6-one in an acidic medium proceeds at the C-2 atom and leads to 2-(indol-3-yl)-4-methyl-2-trifluoromethyl-2,3-dihydro-1,3-oxazin-6-ones in 67–83% yields. Pyrroles and N,N-dimethylaniline either do not enter into a reaction of this type or form the addition products in very low yields (6–12%).

4-甲基-2-三氟甲基-1,3-恶嗪-6-与吲哚的反应

在酸性介质中将吲哚添加到4-甲基-2-三氟甲基-1,3-恶嗪-6-酮中的过程是在C-2原子处进行的,并导致生成2-(吲哚-3-基)-4-甲基- 2-三氟甲基-2,3-二氢-1,3-恶嗪-6-一的产率为67-83%。吡咯和NN-二甲基苯胺不会进入这种类型的反应,或者会以极低的收率(6-12%)形成加成产物。
