Sažetak

By applying the method used by Pfister et al. for the synthesis of threonine we prepared DL-a-amino-B-hydroxy-valeric acid (hydroxynorvaline) starting from ethyl B-keto-valerate. This amino acid was prepared earlier by different methods by Osterberg , Abderhalden and Heyns , Botviillii.k et al, Euston et al., and by Izumiya. The melting points of hydorxynorvaline and of its N-benzoyl derivate indicate that the product obtained consists mainly of the threo-isomer.
