7-Phenyl-13H-indolo[3,2-c]acridines (2a–e) have been prepared from 2,3,4,9-tetrahydro-1H-carbazol-1-ones (1a–e) via the intermediate 5,6-dihydro-derivatives (3a–e), and 13H-indolo[3,2-c]acridines (8a–e) from the 1-(N-phenylamino)carbazoles (7a–e). Methylations of 2 and 8 have been carried out, and UV spectral studies on the title compounds and the methylated products are presented, along with plausible mechanisms for the formation of the final compounds.
