(S)-4-Methyloxazolidin-2,5-dion Chemische Eigenschaften,Einsatz,Produktion Methoden

Verwenden

(S)-4-Methyl-2,5-oxazolidonedione is composed of oxazolidine ring and 2,5-dione ring. It exhibits chirality, meaning it exists as two non-superimposable mirror image forms. Therefore, it can be used as an organic reagent for the synthesis of enantiomeric pure substances. (S)-4-Methyl-2,5-oxazolidonedione is a reagent used in the synthesis of poly(γ-benzyl-L-glutamate) and its block polypeptides with alanine, leucine and phenylalanine.

Vorbereitung Methode

L-alanine (20.0 g, 0.224 mol) and triphosgene (53.4 g, 0.180 mol) were suspended in 400.0 mL of dry THF bubbled with nitrogen flux in a flame-dried three-neck flask. The mixture was stirred at 60 °C for 2 h before further bubbling with nitrogen flux for 30 min. After that, the solution was precipitated in 1000.0 mL of n-hexane and stored at -20 °C. The supernatant was removed, and the residues were collected and dissolved in 200.0 mL of ethyl acetate, before two washings with 100.0mL of ice-cold water and one washing with 100.0 mL of 0.5% NaHCO3 ice-cold aqueous solution. The organic phase was then dried over anhydrous MgSO4 and evaporated to obtain 15.5 g of L-Ala NCA ((S)-4-Methyl-2,5-oxazolidonedione). The yield of L-Ala NCA was 77.5%.
