Reaction Steps

The synthesis of 4-aminooxybutyric acid and 5-aminooxyvaleric acid are described in Tetrahedron, 23, 4441 (1967). Benzophenone oxime in N-methylpyrrolidone is reacted first with sodium then with γ-butyrolactone to provide N-diphenylmethylidene-4-aminooxybutyric acid which is subsequently hydrolyzed to form 4-aminooxybutyric acid. 5-aminooxyvaleric acid hydrochloric acid salt is prepared similarly by substituting γ-butyrolactone with γ-valerolactone. Aminooxyacetic acid is available as the hemihydrochloride from a commercial source.
