The reactions in benzene of 9-alkyl-3-aminocarbazoles with ethyl-3-oxobutanoate yielded ethyl-3-[(9-alkyl-9H-carbazol-3-yl)amino]but-2- enoate condensation products or N-(9-ethyl-9H-carbazol-3-yl)-3-oxobutanamide acylation products. The condensation products were cyclized to the corresponding 4,7-dihydro-pyrido[2,3-c]-carbazol-1-ones upon heating in mineral oil at 240-250 °C. The structures of the synthesized compounds were investigated by IR, mass spectrometry, 1H- and 13C-NMR spectroscopy and MM2 molecular mechanics and AM1 semi-empirical quantum mechanical methods.
