It was established that polymethyl-substituted 2-azafluorences obtained by catalytic dehydrocyclization of pyridine- and benzene-ring-substituted ?-arylpyridines have different structures depending on the position of the methyl groups in the starting compound and which methyl group participates in the cyclization reaction. The 1,4, 7-trimethyl-2-azafluorene synthesized by this method was used for the preparation of new condensed heterocyclic systems of the 3-azafluoranthene and cyclohexano-8-azafluoranthene type. |
