The present invention relates to aniline derivatives of the general formula (I) or salts thereof and their use, related to their KCNQ potassium ion channel opening activity.
showed high efficiency for the couplingreactions of aminoacids and inactive aryl halides to give N-aryl aminoacids. Under the catalytic conditions, not only α-amino acids, but also β-, γ-, and δ-amino acids have been coupled with aryl chlorides in moderate to high yields; in the case of optically pure β-amino acids as substrates, the optical purities of the coupling products retained.

A mild and efficient method for the N-arylation of zwitterionic amino acids, amino acid esters and peptides is described. The procedure provides the first roomtemperature synthesis of N-arylated amino acids and peptides using CuI as a catalyst, diketone as a ligand, and aryliodides as coupling partners. The method is equally applicable for using relatively inexpensive aryl bromides as coupling partners
