Synthesis, structure, and antitumor activity of 2,9-disubstituted perhydro 2,3a,7b,9,10a,14b-hexaazadibenzotetracenes

Recent Advances in the Chemistry of Saturated Annulated Nitrogen-Containing Polycyclic Compounds

This review is devoted to the analysis of works published over the past 20 years on the chemistry of saturated annulated nitrogen-containing polycyclic compounds, the molecules of which consist of four, five, six, and seven cycles, and contain from one to eight endocyclic nitrogen atoms.

N-Substituted tetrahydropentaazadibenzocycloheptafluorenes – a new type of condensed polyazapolycyclic system

Ni-Catalyzed heterocyclization of octahydro-2,2′-biquinazoline with 1,3,5-triazinanes is an efficient synthetic route to mono-N-substituted tetrahydro-4b,5a,10b,12,13a-pentaazadibenzo[a,h]-cyclohepta[1,2,3,4-def]fluorenes.
