Abstract


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%).


Keywords


indoles, 2-(indol-3-yl)-4-methyl-2-trifluoromethyl-2,3-dihydro-1,3-oxazin-6-ones, 1,3-oxazin-6-one, pyrroles, nucleophilic addition.
