Novel Imidazole and Dibenzothiophene-dioxideContaining Tetracyclic Systems

摘要

The aim of the current work is synthesis of new heterocyclic teratacyclic condensed systems that combine dibenzothiophenedioxide and imidazole in one molecule. The dibenzothiophene was taken as an initial compound and by consistent expansion were connected the imidazole cycles. As a result two new tetratacyclic systems 3H-imidazole[4,5-b]dibenzothiophene-5,5dioxide and 3H-imidazole[4,5-a] dibenzothiophene-5,5dioxide were produced. The spectral property of obtained systems were investigated.
