Copper-Catalyzed Direct Arylation of Cyclic Enamides Using Diaryliodonium Salts

[摘要]：A convenient method for the copper(II)-catalyzed direct arylation of cyclic and nonaromatic enamides using diaryliodonium salts has been developed. The reaction demonstrates large functional group tolerance, good yields, and total regioselectivity with a C(3)-functionalization. The synthetic potential of this coupling was explored by using a range of readily accessible diaryliodonium salts and enamides.
