to quinazoline derivatives has been developed, and the protocol uses readily available substituted (2-bromophenyl)methylamines and amides as the starting materials, and the cascade reactions were performed under air via sequential Ullmann-type coupling and aerobic oxidation without addition of any ligand or additive. The present method provides a convenient and practical strategy for synthesis of quinazoline
An efficient Cu-catalyzed synthesis of quinazolines via the C–N bond formation reactions between N–H bonds of amidines and C(sp3)–H bonds adjacent to sulfur or nitrogen atoms in the commonly used solvents, such as DMSO, DMF, DMA, NMP or TMEDA, followed by intramolecular C–C bond formation reactions was developed for the first time.
