Copper-Catalyzed Coupling Reaction of (Hetero)Aryl Chlorides and Amides

Copper-Catalyzed Coupling Reaction of (Hetero)Aryl Chlorides and Amides
Subhadip De, Dawei Ma, Junli Yin
Cu2O/N,N′-bis(thiophen-2-ylmethyl)oxalamide is established to be an effective catalyst system for Goldberg amidation with inferior reactive (hetero)aryl chlorides, which have not been efficiently documented by Cu-catalysis to date. The reaction is well liberalized toward a variety of functionalized (hetero)aryl chlorides and a wide range of aromatic and aliphatic primary amides in good to excellent yields. Furthermore, the arylation of lactams and oxazolidinones is achieved. The present catalytic system also accomplished an intramolecular cross-coupling product.
