- Copper-catalyzed synthesis of N-aryl acridones from 2-amino benzophenones and aryl boronic acids via sequential double oxidative C–N coupling
-
Pot-economic synthesis of N-aryl acridones was performed with 2-aminobenzophenones and aryl boronic acids as starting materials. Cu-catalyzed chelation-assisted oxidative C–N cross-coupling reactions were well merged with the following intra-molecular oxidative dehydrogenative C–H amination reactions under an air atmosphere. The use of reagent capsules can further resolve the compatibility problem of reagents and simplify the operational process, providing a more straightforward access to the target products.

- Copper-catalyzed intramolecular direct amination of sp2 C-H bonds for the synthesis of N-aryl acridones
-
A copper-catalyzed approach for the synthesis of N-aryl acridones via sp2 C-H bond amination using air as oxidant under neutral conditions is disclosed. This reaction not only provides a complementary method for synthesizing medicinally important acridones, but also offers a new strategy for sp2 C-H bond amination.

- Formation of acridones by ethylene extrusion in the reaction of arynes with β-lactams and dihydroquinolinones
-
N-Unsubstituted β-lactams react with a molecule of aryne by insertion into the amide bond to form a 2,3-dihydroquinolin-4-one, which subsequently reacts with another molecule of aryne to form an acridone by extrusion of a molecule of ethylene. 2,3-Dihydroquinolin-4-ones react under the same reaction conditions to afford identical results. This is the first example of ethylene extrusion in aryne chemistry.
