| Abstract: | A method for the synthesis of 4-alkylpolymethylindoles by recyclization of 4-alkyl-2,6-dimethyl-3-nitropyridine methiodides in the presence of ketones was developed. A method for establishing the structures of the polyalkylindoles on the basis of data from the PMR spectra and the proton-coupled 13C NMR spectra is proposed.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 509–518, April, 1985. |
