Abstract: | Alkylation of 4a-methyl-, 4a,6-dimethyl- and 6-bromo-4a-methyl-2,3,4,4a-tetrahydro-1H-carbazoles using 2-chloromethyl-4-nitrophenol gives 1,3]benzoxazino2,3-k]carbazoles. Derivatives of 2,4]benzodiazepino3,2-k]carbazole have been synthesized by alkylation of the indicated carbazolenines using 2-bromomethylbenzonitrile followed by hydrolysis of the nitrile group of the 9-(2-cyanobenzyl)-carbazolium salts obtained to amide.Kaunas Technological University, Kaunas, LT-3028, Lithuania Translated from Khimiya Geterotsiklichenskikh Soedinenii, No. 6, pp. 818–821, June, 1999. |
