Palladium-catalyzed coupling reaction of amino acids (esters) with aryl bromides and chlorides
Ma, Fangfang,Xie, Xiaomin,Ding, Lina,Gao, Jinsheng,Zhang, Zhaoguo
experimental part, p. 9405 - 9410 (2011/12/14)
The bulky and electron-rich MOP type ligands and Pd(dba)2 combinations showed high efficiency for the coupling reactions of amino acids and inactive aryl halides to give N-aryl amino acids. 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.
