Construction of rings through reliable reactions followed by changes in the ring size or the connectivity through skeletal rearrangement provides molecules with a wide range of skeletons. In this account, our syntheses of polycyclic natural products through skeletal rearrangement are discussed. 1 Introduction 2 Synthesis through Changes in the Ring Size 3 Synthesis by Biomimetic Strategies 4 Synthesis through Metathesis 5 Synthesis through Temporary Formation of a Ring 6 Conclusion
