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使绝缘 发表于 2025-3-23 14:07:01
,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 straCOMMA 发表于 2025-3-23 20:43:01
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 creaepidermis 发表于 2025-3-24 01:07:48
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-AVID 发表于 2025-3-24 03:57:01
