  Biheteroarenes,possess a privileged structural cores in organic functional materials,ligands,and biological activities.[1] Moreover,aminated alkylthiophenes by utilizing azoles as the amination reagent are often employed as the building blocks in pharmaceuticals,such as glucagon receptor antagonists,inhibitors of ITK kinase and inhibitors of KV 1.5.
