Cyclization of N-diacetic amino acids
Shvedaite
, p. 1185 - 1188 (1998)
Cyclization of a number of N-diacetic amino acids has been carried out. The dependence of the cyclization products - 3,5-dioxopiperazinoalkanecarboxylic acids and/or their amides - on the temperature, ratio of components, and the presence of solvent has b
Nitrilotriacetamide: Synthesis in concentrated sulfuric acid and stability in water
Smith,Sucheck,Cramer,Baker
, p. 4123 - 4132 (2007/10/03)
Acid hydrolysis of N(CH2CN)3 leads either nitrilotriacetamide, 1, and/or 3,5-dioxopiperazineacetamide, 4, in quantitative yield. 1 slowly and cleanly converts to 3,5-dioxopiperazineacetic acid, 5, in water, although ammonium salts prevents this reaction.
