| Abstract: | 4 -Hydroxy-3-methyl-2,6-diphenyl-3ethoxycarbonylspiro(2-azafluorene-9, 1-cyclohex-3-ene) was obtained by condensation of 3-methyl-2-azafluorene with ethyl cinnamate in the presence of potassium. The chemical mechanism of its formation and its three-dimensional structure are discussed.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 9, pp. 1231–1234, September, 1976. |
