Carcinogenic nitrogen compounds. Part LVII. Hexacyclic acridines derived from phenanthrene and fluorene
Abstract
The use of 9- and 2-aminophenanthrene for the preparation of tribenzo- and benzonaphtho-acridines and related heterocycles has been investigated; with 2-aminophenanthrene, the site of the acridine cyclisations is shown to be position 1. Benzoindenoacridines isosteric with benzonaphthoacridines were prepared from 4-aminofluorene.
