First Example of Catalytic Synthesis of Difurazanohexahydrohexaazapyrenes and in Vitro Study of Their Antitumor Activity

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.

Access to diverse primary, secondary, and tertiary amines via the merger of controllable cleavage of triazines and site-selective functionalization

An efficient approach for divergent synthesis of primary, secondary, and tertiary amines via the merger of controllable cleavage of triazines and site-selective functionalization is disclosed.

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

Catalytic methods for the synthesis of previously unknown 2,9-disubstituted 3bR*,7aR*,10bR*,14aR*-cis-14c,14d-perhydro-2,3a,7b,9,10a,14b-hexaazadibenzotetracenes have been developed. The structures were established by 1D (¹H, ¹³C) and 2D (COSY, HSQC, HMBC) NMR spectroscopy, MALDI TOF/TOF mass spectrometry, and X-ray diffraction analysis. Primary screening of the synthesized perhydro hexaazadibenzotetracenes for antitumor activity was carried out.
