First Synthesis of 2,9-Disubstituted cis-2,3a,7b,9,10a,14b- Hexaazaperhydrodibenzotetracenes

Abstract

The first synthesis of 2,9-disubstituted cis-2,3а,7b,9,10a,14b-hexaazaperhydrodibenzotetracenes has been accomplished through intermolecular heterocyclization of N,N-bis(methoxymethyl)alkylamines with cis-1,6,7,12-tetraazaperhydrotetracene in the presence of SmCl3·6H2O catalyst or by recyclization of 1,3,5-tricycloalkyl-1,3,5-triazinanes with cis-1,6,7,12-tetraazaperhydrotetracene in the presence of NiCl2·6H2O catalyst. The structures were established by 1D (1H, and 13C) and 2D (HSQC, HMBC, COSY, NOESY) NMR spectroscopy, MALDI TOF/TOF mass spectrometry, and X-ray diffraction analyses.
