Transformations of the sulfur analogs of Β-carbolins under the influence of nucleophiles

The reaction of the quaternary salts of some thienopyridines (the sulfur analogs of -carbolins) with nucleophilic reagents was investigated. It was shown that either the methylene anhydro bases are formed or one or both heterocyclic rings are transformed, depending on the structure of the thienopyridine and on the reaction conditions.For the previous communication, see [1].Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 3, pp. 398–403, March, 1987.
