A new mode of activation : The asymmetric diarylprolinol‐catalyzed α‐sulfenylation of β‐ketoesters provides the products in good‐to‐excellent enantioselectivities and yields. Studies suggest that the sterically bulky secondary amines activate β‐ketoesters through hydrogen bonding. Lg=leaving group.
