An efficient pot-economic and step-economic RhIII-catalyzed site-selective direct amination/annulation strategy was developed for the synthesis of benzophenanthroline derivatives using quinoline N-oxides and anthranils. The method was further extended to the synthesis of nitrogen-containing extended π-conjugated benzophenanthrolinone derivatives. Late-stage functionalizations of cinchonidine and cinchophen derivatives and synthesis of a bioactive quinolino-indole were achieved.

The invention discloses a method for synthesizing quinoline oxynitride from a quinoline compound by ultrasonic-assisted oxidation. The quinoline compound and hydrogen peroxide are subjected to nitrogen oxidation reaction under the ultrasonic-assisted condition and perfluorosulfonic acid resin (Nafion-H) catalytic action to obtain quinoline oxynitride. The method has the advantages that the raw materials are easy to obtain, reaction conditions are simple and mild, greenness and energy conservation are achieved, and reaction selectivity and yield are high; energy is saved and the compatibility of substrate functional groups is excellent; in particular, the perfluorosulfonic acid resin can be recycled as an acid catalyst, so that not only is the reaction cost reduce, but also the reaction yield is increased, also the pollution problem in traditional oxidation reaction is avoided and a relatively high application value is achieved.

An efficient copper(I)-catalyzed direct regioselective arylamination of various heterocyclic N-oxides was achieved successfully under redox-neutral conditions using anthranils as arylaminating reagents. The developed protocol is simple, straightforward, and economic with a broad range substrate scope. The dual functional groups in the final molecules were utilized to construct structurally and functionally diverse nitrogen-containing organic π-conjugated systems.
