Amide nucleophiles on demand : Rationally designed pyrazoleamides function as Michael donors in urea‐catalyzed asymmetric Michael reactions with excellent chemical and optical yields (see scheme). The pyrazoleamide group performs as an ester equivalent, a directing group, an activating group, and functions as a good leaving group in further transformations of the product.
