Zusammenfassung:
The first highly efficient asymmetric epoxidation of 2-cyclopentenones has been developed. Using a newly designed and readily available Cinchona amine catalyst, 2-cyclopentenones are reacted with hydrogen peroxide to give the corresponding epoxycyclopentanones in high yields and excellent enantioselectivities.
