TCI B5613, commercially known as Jacobsen's catalyst, is a chiral manganese(III)-salen complex widely employed for highly enantioselective epoxidation of unfunctionalized alkenes. It is also utilized in asymmetric ring-opening reactions, enantioselective sulfide oxidation, and various other stereoselective transformations critical in medicinal chemistry and natural product synthesis. This compound is an essential tool for research laboratories focused on asymmetric catalysis and chiral building block preparation.
