A Titanium-Catalyzed Three-Component Coupling To Generate α,β-Unsaturated β-Iminoamines

Abstract
The three-component coupling of an amine, alkyne, and isonitrile is facilitated by a titanium complex bearing the N,N-di(pyrrolyl-α-methyl)-N-methylamine (dpma) ligand. From this methodology, α,β-unsaturated β-iminoamines are generated regioselectively with many substrates and are available on multigram scales.
