from 2-bromobenzamides and 2-bromo(thio)phenols via twice copper-catalyzed couplings to afford dibenzothiazepines and dibenzoxazepinones has been developed. High levels of yield and chemoselectivity are achieved in a single-pot reaction by using an appropriate ligand. Moreover, this facile methodology allows rapid access to a variety of bioactive compounds and known psychotropic drug, which should

An efficient and practical copper-catalyzed one-pot method for synthesis of tetrahydroisoquinolino[2,1-a]quinazolinone derivatives has been developed, and the corresponding target products were prepared in moderate to good yields. The one-pot approach underwent sequential copper-catalyzed N-arylation, intramolecular aerobic oxidative cyclization, and the newly synthesized products provided diverse structures for screening of biological molecules.
A facile method for the preparation of 2-thioxo-2,3-dihydropyrido[3,2-e]-1,3-thiazin-4-ones by the reaction of N-alkyl-2chloropyridine-3-carboxamides with carbon disulfide in the presence of sodium hydride as a base has been developed.

A simple, practical, and highly efficient copper‐catalyzed one‐pot synthesis of imidazo/benzoimidazoquinazolinones has been developed. The procedure is based on a sequential copper‐catalyzed Ullmann‐type N‐arylation and aerobic oxidative intramolecular CH amidation. This method should provide a new and useful strategy for construction of N‐heterocycles.
