Enantioselective Synthesis of Chiral Amides by a Phosphoric Acid Catalyzed Asymmetric Wolff Rearrangement**
The highly enantioselective synthesis of chiral amides was achieved by an asymmetric Wolff rearrangement. A bifunctional phosphoric acid catalyst not only expedited the transformation but also controlled the enantioselectivity. The developed method enables the asymmetric addition between potent nucleophilic reagents and ketene species and provides a new approach to chiral amides.
