Cu(I)/Chiral Vanadium Complex Cooperatively Catalyzed Asymmetric Sulfonation/Rearrangement of Alkenylfurans.

The asymmetric three-component rearrangement of alkenylfurans with various sulfonyl chlorides and anilines is developed via copper(I) and chiral vanadium cooperative catalysis, providing a facile access to a broad spectrum of sulfonyl-functionalized 4-aminocyclopentenones in high yields with excellent enantio- and diastereoselectivities.
