General chemical structure of a selone

In chemistry, a selone is the structural analog of a ketone where selenium replaces oxygen. Selones are used as chiral derivatizing agents for selenium-77 NMR spectroscopy.[1] Chiral oxazolidineselones are excellent partners in the stereospecific aldol reaction, and 77Se NMR can verify the enantiomeric purity of the aldol product.[2]
