Nitrogen-rich zole-ring compounds, as significant N-heterocyclic compounds, have a wide range of ap-plications in medicinal chemistry, bio-conjugation, materials chemistry, etc. The syntheses of nitro-gen- rich zole-ring compounds by cycloaddition reaction have been paid more and more attention. This review is focused on research progress in synthesis of nitrogen-rich zole-ring compounds by cycloaddition reaction in recent years from various aspects such as the type of catalysts, synthesis of differently substituted products, etc.

Key words: nitrogen-rich zole-ring, cycloaddition reaction, review
