Abstract: | The reactions of quaternary salts of 3-pyridyl- and benzopyridylindoles with alkali proceed via two pathways, viz., deprotonation, the products of which are anhydro bases, and dealkylation of the pyridine ring, as a consequence of which the corresponding nonquaternized bases are formed. The reactions are interpreted from a quantum-chemical point of view.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 7, pp. 959–964, July, 1980. |
