Abstract: | The addition of benzene to 2,2,4-trimethyl-1,2-dihydroquinoline (I) in the presence of AlCl3 requires prior protonation or acylation of the amino group. Electron-donor substituents in the benzene ring of I hinder the reaction. The addition of halobenzenes proceeds under more severe conditions to give only para-substituted 4-aryl-2,2,4-trimethyl-1,2,3,4-tetrahydroquinolines.See 1,2] for communications I and II.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 6, pp. 795–797, June, 1971. |
