GLYCINE ANHYDRIDE Chemical Properties,Usage,Production
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).
