Reaction schemes which involve successive cleavage and formation, or vice versa, of carbocyclic and/or heterocyclic compounds, are reviewed. These processes are quite effective for constructing complex natural products. Ring transformation is chosen as an example for successive cleavage and formation of cyclic compound. Successive formation and cleavage of cyclic compound are discussed for stereospecific introduction of substituent (s) into monocyclic compound via bicyclic one.
These two types of reaction schemes are illustrated by the use of recently reported syntheses of natural products including sesquiterpenes, prostaglandins, steroids, alkaloids, etc.
