Ring Expansions of Azirines and Azetines,e prepared starting from these strained compounds due to their extremal reactivity involving nucleophilic, electrophilic, and metal-catalyzed additions, cycloadditions of different types, and thermal and catalytic isomerizations. Although the chemistry of azetines is not so diverse, some specific he

,Ring Expansions of β-Lactams and β-(thio)lactones,cs such as penicillins and cephalosporins. On the other hand, there are several natural products containing a β-lactone moiety, with interesting inhibitory activity. In addition, both fragments are very useful synthetic intermediates for the preparation of cyclic and acyclic compounds. The ring stra

Ring Expansions of Oxiranes and Oxetanes,substrates, the discussion of which is broken into five thematic sections representing insertions, cascades, metal-free, metal-catalyzed, and miscellaneous strategies. Oxetane ring-expansion reactions are still rare and are discussed together in one section. A concise graphical summary has been crea

Synthesis of Four- to Seven-Membered Heterocycles by Ring Expansion: Ring Expansions of Thiiranes aanes and azetidines). They have been widely applied in the preparation of sulfur-containing compounds. Thiiranes undergo ring expansions to generate various four-, five-, six-, and seven-membered heterocyclic products, even larger heterocycles. Thietanes also undergo ring expansions to produce five-
