摘要
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%).
