A Cu-catalyzed tandem synthesis of azole-fused pyrimido[1,2-c]quinazolines and imidazo[1,2-c]quinazolines has been developed. The reaction is based on a C–N cross-coupling/C–H functionalizationreaction of 2-(2-bromophenyl)-1,4,5,6-tetrahydropyrimidines with azoles. A variety of the desired polycyclic products were obtained in moderate to excellent yields.

Synthesis of novel azole-fused quinazolines via one-pot, sequential Ullmann-type coupling and intramolecular dehydrogenative C–N bonding
An efficient one-pot sequential procedure is described for the synthesis of novel azole-fused quinazolines through Ullmann-type coupling followed by cross dehydrogenative coupling of various azoles with 2-(2-bromophenyl)-1H-imidazole/benzimidazoles.
the assembly of novel polycyclic benzimidazole derivatives has been developed by Cu-catalyzed domino addition/double cyclization reactions. A wide variety of polycyclic benzimidazole derivatives, which might be used as synthetic medicines and functional materials, were successfully assembled from bis-(o-haloaryl)carbodiimides. Unexpected N-methylated benzo[4,5]imidazo[1,2-a]indoles can also be selectively

A new synthetic method of trinuclear N‐fused hybridscaffolds has been developed by copper‐catalyzed C–N coupling and cycloconedensation of 2‐(2‐bromoaryl)‐ and 2‐(2‐bromovinyl)‐benzimidazoles with cyclicureas as newbuildingblocks. Further studies on the synthesis of polynuclear N‐fused hybridscaffoldsusing this protocol are expected.
