Article abstract of DOI:10.1246/bcsj.62.2748

When anhydrides of N-benzyloxycarbonyl-DL-aspartic acid (Z-DL-Asp), Z-L-Asp, N-Z-DL-glutamic acid (Z-DL-Glu), Z-L-Glu and N-Z-3-aminoglutaric acid (Z-β-Agl) were hydrogenolyzed in N,N-dimethylformamide (DMF), polypeptides were obtained in high yields.Hydrogenolyses of Z-DL-Glu and Z-L-Glu in dioxane gave pyroglutamic acid.
