Abstract
A systematic racemization study of the coupling of Z-Phe with Phe-OBzl has been carried in order to determine the optimal conditions. It is found that the L,D diastereomer is the favored product in the coupling of Z-L-Phe with D,L-Phe-OBzl. A possible mechanism is proposed and elucidated by NMR studies.
