✦ Synopsis
The recent findings of Campbell et al. (I) regarding the action of L-asparaginase on various asparagine-requiring tumours have prompted the syntheses and investigation of analogues of this amino acid (2).
We wish to report the preparation of the F-amides of three-and erythr@-~-hydroxy-L-aspartic acids by ammonolysis of O-benzyl threo-O-hydroxy-L-aspartate
