Enantioselective Ene Reaction of Cyclopentadiene and α,β‐Enals Catalyzed by a Diphenylprolinol Silyl Ether

Abstract

The opposite result: A diphenylprolinol silyl ether promotes an intermolecular enantioselective ene reaction of α,β-enals with cyclopentadiene. This is the first example of cyclopentadiene acting as the ene component, and not the diene, with α,β-enals.
