| | GLYCINE ANHYDRIDE Usage And Synthesis |
| Chemical Properties | white to slightly yellow crystalline powder | | Uses | 2,5-Piperazinedione, can be used as an intermediate in the preparation of various pharmaceutical and biologically active compounds. It can be used in the synthesis of dipeptide isosteres by cross-metathesis. | | Definition | ChEBI: A cyclic peptide that is piperazine in which the hydrogens at positions 2 and 5 are replaced by oxo groups. | | Synthesis Reference(s) | Journal of the American Chemical Society, 87, p. 4646, 1965 DOI: 10.1021/ja00948a047 | | Purification Methods | Recrystallise glycine anhydride from H2O (plates) and it can be sublimed (slowly) at 260o or at 140-170o/0.5mm. The dihydrochloride has m 129-130o and is prepared by dissolving it in conc HCl and adding EtOH to crystallisation point; dry it in a vacuum. The bis-1-naphthylurethane has m 232o(dec), and the diperchlorate has m 117o (hygroscopic).
