title: Synthesis of N-Propargylsulfoximines by Copper-Catalyzed A3-Couplings.
abstract: An efficient synthesis of N-propargylsulfoximines was developed through a copper-catalyzed coupling of aldehydes, alkynes, and NH-sulfoximines. The reaction requires no co-catalyst or ligand and shows a wide substrate scope with moderate to good yields.
