Ring-Closure Reactions

Ring-closure reactions are chemical processes where a chain-like molecule forms a loop by connecting its two ends through a chemical bond. This transformation creates a cyclic (ring-shaped) compound from an open-chain precursor. Such reactions are important in synthesizing rings found in natural products, pharmaceuticals, and materials. The process often involves the molecule’s reactive sites coming together and forming a stable ring structure, which can influence the molecule’s stability and reactivity. Overall, ring-closure reactions are key pathways in the formation of complex, cyclic molecules in chemistry.
