A series of novel peri-fused azines, pyrimido[4,5,6-de]quinolino[2,3-b][1,8]naphthyridines and benzo[b]pyrimido[4,5,6-de][1,8]naphthyridines, were prepared via the base-promoted double tandem cyclization of 4-(1-acyl-2,2-diaminovinyl)-6-(haloaryl)pyrimidine-5-carbonitriles. This transformation represents a rare example of the one-pot synthesis of peri-annulated polycyclic structures from non-fused heterocycles. The synthesized pyrimido[4,5,6-de]quinolino[2,3-b][1,8]naphthyridines were found to be luminophores.
