Hazard Information | Back Directory | [Description]
?N,N'-diacetylglycine anhydride, also known as diacetylated glycylglycine, can be obtained by acylation of glycylglycine with acetic anhydride. N,N'-diacetylglycine anhydride can be used to prepare DL-neopentylglycine derivatives. | [Application]
N,N'-diacetylglycine anhydride can be used as organic synthesis intermediate and pharmaceutical intermediate, mainly used in laboratory research and development process and chemical and pharmaceutical synthesis process. | [Preparation]
After the mixed reaction of glycylglycine and acetic anhydride, ethyl acetate and petroleum ether are added in sequence to obtain the intermediate N,N'-diacetylglycine anhydride. | [Synthesis]
GENERAL METHOD: 2,5-Piperazinedione (500 mg, 2.5 mmol) was mixed with ethanoic anhydride (20 mL) and reacted at 150°C overnight. Upon completion of the reaction, the excess acetic anhydride was removed by distillation under reduced pressure. The residue was purified by silica gel column chromatography to afford 1,4-diacetylpiperazine-2,5-dione. | [References]
