Cyclopropenes and methylenecyclopropanes in 1,3-dipolar cycloaddition reactions

The review considers the main results of the cycloaddition reactions involving cyclopropenes and methylenecyclopropanes, the compounds bearing strained three-membered rings and, respectively, endo- and exocyclic double bonds. The main attention is focused on the reactions of these compounds with 1,3-dipoles (nitrones, azomethine imines, azomethine ylides, carbonyl ylides, etc.), which gave complex heterocyclic systems with high regio- and stereoselectivity.
