An asymmetric copper‐catalyzed Sonogashira type coupling between alkynes and α‐bromoamides has been developed. This method represents a facile approach to synthetically useful β, γ‐alkynyl amides from two readily available starting materials in a highly enantioselective manner. A Bisoxazoline diphenylanaline (BOPA) serves as the effective chiral ligand. Preliminary mechanistic studies support the formation
