Application

(1R)-(+)-Nopinone may be used in the preparation of a chiral annulated indene derivative, which can be a potentially useful chiral ligand for transition metal complexes in asymmetric transformations.[1] It may also react with secondary amines in cyclohexane to form the corresponding enamines.[2]
