The rapid generation of molecular in a relatively easy manner has made the cycloaddition reaction a powerful tool in the synthesis of different membered ring compounds.Clearly,iron catalysts are becoming a much more interesting and viable choice for this purpose.In this review,a number of promising results in the iron catalyzed cycloaddition reactions in the last decades were summarized.Special attention has been paid to the asymmetric cycloaddition reactions.
