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

摘要

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 SmCl_(3)·6H_(2)O catalyst or by recyclization of 1,3,5-tricycloalkyl-1,3,5-triazinanes with cis -1,6,7,12-tetraazaperhydrotetracene in the presence of NiCl_(2)·6H_(2)O catalyst. The structures were established by 1D (~(1)H, and ~(13)C) and 2D (HSQC, HMBC, COSY, NOESY) NMR spectroscopy, MALDI TOF/TOF mass spectrometry, and X-ray diffraction analyses.
