A novel copper-promoted N-arylation of enaminones with aromatic boronic acids has been developed, which provides an efficient way to synthesize N-aryl enaminones with a broad substrate scope and excellent functional group compatibility. The N-aryl enaminones could be converted into a series of highly valuable building blocks and bioactive compounds. Notably, in comparison with traditional methods, this alternative approach provides accesses to N-aryl enaminones bearing multiple aromatic rings.

About specifics: A method for the regiospecific synthesis of the title compounds through an unprecedented Michael addition/deacylative diazo transfer/cyclization sequence has been established. The simple and practical method can be used for the modification of primary amines including chiral α-amines. The process involves the formation three covalent bonds and the cleavage of two covalent bonds (see scheme, Ts=4-toluenesulfonyl).

A variety of functionalities, including the whole range of halogen substituents, are tolerated in the title reaction, an intramolecular approach for the construction of a multisubstituted indole skeleton from readily available enaminones (see scheme; phen=1,10-phenanthroline). The indole products are also prepared directly in high yield from α, β-ynones and primary amines.
