O-(2,4-Dinitrophenyl)hydroxylamin Chemische Eigenschaften,Einsatz,Produktion Methoden
Chemische Eigenschaften
Light yellow solid
Verwenden
O-(2,4-Dinitrophenyl)hydroxylamine is a rapid active-site-directed inhibitor of D-amino acid oxidase; modification results in specific incorporation of an amine group into an accessible nucleophilic r
esidue with concomitant release of 2,4-dinitrophenol.
synthetische
To a stirred solution of 13.3 gm (0.1 mole) of t-butyl JV-hydroxycar-bamate and 5.6 gm (0.1 mole) of potassium hydroxide in 200 ml of absolute ethanol is added 20.2 gm (0.1 mole) of 2,4-dinitrochlorobenzene. The resultant deep red solution is stirred at room temperature for 1 hr; then enough glacial acetic acid is added dropwise to produce a light yellow solution. The solution is poured into 1.5 liters of cold water. The yellow oil which separates is gradually converted to crystals. The solid ?-butyl JV-(2,4-dinitrophenoxy)carbamate is separated, dried, and recrystallized from an ethyl acetate-hexane mixture to afford 16.4 gm (53%), m.p. 74-75°C. To 15 ml of trifluoroacetic acid is added 4 gm (0.0133 mole) of the i-butyl J/V-(2,4-dinitrophenoxy)carbamate. After the evolution of carbon dioxide has subsided, the solution is poured into 100 ml of ice water. The resultant oily layer crystallizes on standing to afford 2.5 gm (95%), m.p. 112°C (from ethanol).
Recently it was discovered that the alkylation of ethyl JV-hydroxy-carbamate under alkaline conditions, particularly in a DMF medium at 60°C in the presence of sodium bicarbonate, leads to the ultimate formation of O-alkylated hydroxylamines. On the other hand, at 80-85°C, the direct alkylation without the presence of a base ultimately leads to N-alkylhydrox-ylamines (see Table I) [59]. The reaction of ethylazidoformate with an alcohol, while perhaps hazardous, may have some merit (Eqs. 31-33). The overall yield, based on ethyl chloroformate, is said to be on the order of 60%.
