CuI-catalyzed coupling reaction of aryl halides with beta-amino acids or beta-amino esters is completed at 100 degrees C in 48 h, which indicates that the structure of the beta-amino acid has an accelerating effect for the Ullmann-type arylamination reaction. This coupling reaction can be used to prepare enantiopure N-aryl beta-amino acids. An efficient syntheticroute to SB214857, a potent GPIIb/IIIa
