Synthesis of new polycyclic adducts based on perhydrotetraazatetracene

New N,N′-disubstituted perhydrohexaazadibenzo[fg,op]tetracenes with the (R*,R*,R*,R*) configuration of the chiral centers were synthesized by a one-pot catalytic heterocyclization of perhydrotetraazatetracene with formaldehyde and various primary amines as well as by the catalytic recyclization reaction of 1,3,5-trisubstituted 1,3,5-triazinanes with perhydrotetraazatetracene. The structures of all synthesized compounds were confirmed by NMR spectroscopy and high-resolution mass spectrometry.
