Zusammenfassung:
From the bromination products of l-phenylalanine we recently isolated and identified the following optically pure substances: 2-bromophenylalanine, 4-bromophenylalanine, a small amount of 2,3-dibromophenylalanine, 2,5-dibromophenylalanine, and 3,4-dibromophenylalanine (1). Deuteration of all these compounds except one was studied in order to obtain l-phenylalanines which were labeled in the aromatic ring. Deuteration was carried out on Pd-catalysts with either D2 gas or NaBD4.
