Palladium-Catalyzed Base-Promoted Arylation of Unactivated C(sp<sup>3</sup>)-H Bonds by Aryl Iodides: A Practical Approach To Synthesize β-Aryl Carboxylic Acid Derivatives
A highly efficientprotocol for the β-arylation of carboxylicamides by aryl iodides under PdCl2(CH3CN)2/CsOAc catalysis was developed. This method was found to tolerate a broad scope of substrates and was successfully employed in the preparation of a variety of β-aryl α-amino and γ-amino acid derivatives. The utility of this method was further illustrated in the synthesis of the psychotropic drug
