Heterocyclic compounds are the largely diverse organic molecules and find
prevalent applications in the fine chemical industry, medicinal chemistry and agricultural
science. They are also among the most commonly bearing frameworks in numerous drugs
and pharmaceutical substances. Therefore, the development of convenient, efficient and
environmentally benign methods to produce various types of heterocyclic compounds is
an attractive area of research. For the synthesis and functionalization of heterocycles,
enormous achievements have been attributed over the past decades. Recently, ironcatalyzed
reactions have accomplished a noteworthy development in the synthesis of
heterocycles. This review highlights some remarkable achievements in the iron-catalyzed
synthesis of heterocyclic compounds published in the last five years.
Keywords: Catalysis, iron, earth-abundant transition metal, synthetic methods, five-membered heterocycles, six-membered heterocycles.
