Reactions of dibenzothiazine amination of quinone derivatives on a «copper film»
Abstract
Interest in nitrogen-containing heterocycles can be brought about by the possibility of obtaining organic compounds with new properties by introducing various substituents into the structure. The aim of this work is to aminate quinoid structures with dibenzothiazine to produce condensed heterocycles with a bridged nitrogen atom. It is the N-substituted derivatives that form a bridge between the dibenzothiazine molecule and the substituent that are considered as the most promising substances. When aminating benzoquinone and its derivatives with dibenzothiazine, we can expect an increase in the potential biological activity and inhibitory properties of new compounds. The presence of copper affects the intensity and direction of the reaction when reactants interact. Practice-wise, the work can expand the spectrum of quinone and dibenzothiazine derivatives containing biologically active fragments.
