3‐diynes is described. Key for the success of this novel transformation is the utilization of an advanced palladium catalyst system with the specific ligand Neolephos. The synthetic value of this general approach to synthetically useful α‐alkynyl‐α, β‐unsaturated amides is showcased by diversification of several structurally complex molecules and marketed drugs.

Abstract A one-pot reaction which combines the Cadiot-Chodkiewicz coupling reaction with the Gabrielsynthesis of primary amines is evaluated as a means for the synthesis of unsymmetrically disubstituted aminodiacetylenes of the type CH2-(CH2)n-C≡C-C≡C-CH2-NH2 (n=2,3,4,5).
