new and efficient method for the synthesis of various aza‐fused poly‐hetero aromatics has been described. This protocol includes an intermolecular condensation followed by metal‐free base‐promoted intramolecular C―Ncoupling reaction. The advantage of this one‐pot transformation lies in the use of simple cyclic amidines‐like compounds without prefunctionalization of the starting heterocycles.

Disclosed are a nitrogen-containing fused tricyclic compound, an optical isomer, cis and trans isomers or an agromedically acceptable salt thereof, and the insecticidal use thereof in agroforestry. The delayed working effect of the compound on pests such as red imported fire ants can make the pests carry the drug to a nest, thereby having a better killing effect on the whole red imported fire ants nest and the queen ant.
