Epoxide synthesis is a key organic chemistry reaction converting alkenes into highly reactive epoxides, used in creating complex molecules. It involves oxidation with peroxyacids like mCPBA or the Corey-Chaykovsky reaction for constructing epoxides from carbonyl compounds. Recent advancements include chiral catalysts for asymmetric epoxidation and enzymatic methods for eco-friendly synthesis. Understanding these mechanisms is crucial for applications in pharmaceuticals and material science.
