Synthesis of Propargylamines via Michael Addition Using Methyl Vinyl Ketone Derivatives, 1-Alkynes, and Secondary Amines Catalyzed by Copper (I) Halides
[Image: see text] Propargylamines are synthesized from methyl vinyl ketone derivatives, 1-alkynes, and secondary amines catalyzed by Cu salts involving the Michael addition of amine followed by an unusual C–C bond cleavage and addition of metal acetylides formed in situ to iminium ions. In this appr...

| Sumario: | [Image: see text] Propargylamines are synthesized from methyl vinyl ketone derivatives, 1-alkynes, and secondary amines catalyzed by Cu salts involving the Michael addition of amine followed by an unusual C–C bond cleavage and addition of metal acetylides formed in situ to iminium ions. In this approach, the di-, tri-, and tetrasubstituted propargylamines are synthesized in 46–98% yields. |
