2,3,4,9-四氢-1H-咔唑-1-酮 | 1-oxo-2,3,4,9-tetrahydrocarbazole | 3456-99-3 | C12H11NO | 185.225 |
2-Benzylidene-1,2,3,4-tetrahydrocarbazol-1-ones
2-Benzylidene-1-oxo-1,2,3,4-tetrahydrocarbazoles (1a - e) obtained from the corresponding 1- oxo-1,2,3,4-tetrahydrocarbazoles on reaction with malononitrile in dry benzene with sodium hydride afforded 3-cyano-5,6-dihydro-2-ethoxy-4-phenyl-pyrido[2,3-a]carbazoles (2a - e) in good yields. A plausible mechanism for the formation of the title compound has been proposed and all the compounds were characterised by IR, NMR, mass spectral methods and elemental analysis.
