White to off-white powder | [Uses]
(S)-3-(Boc-amino)butyric acid is used for the syntheses of aza-analogues of macrosphelides, synthesis of hybrid peptides with 12/10-helix, and in the synthesis of potentially pharmaceutically active products for the treatment of auto-immune and inflammatory diseases. | [reaction suitability]
reaction type: Boc solid-phase peptide synthesis | [Synthesis]
Under argon protection, sodium dihydrogen phosphate (7.0 g) and 34.5% aqueous hydrogen peroxide solution (20 mL) were sequentially added to a solution of tert-butyl (S)-(4-oxobutan-2-yl)carbamate (7.3 g, 39.0 mmol) in acetonitrile (50 mL), and the reaction mixture was stirred at 0 °C for 10 min. Subsequently, a solution of sodium chlorite (6.0 g) in water (20 mL) was added dropwise to the reaction system and stirring was continued at 0 °C for 1 hour. Upon completion of the reaction, the reaction was quenched with saturated sodium bicarbonate solution and the aqueous phase was washed with dichloromethane. The aqueous layer was acidified with 10% hydrochloric acid and extracted with dichloromethane, the organic phase was dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The resulting residue was identified by 1H-NMR as carboxylic acid (8) (6.0 g, 29.6 mmol, 76% yield), which could be used in the next reaction without further purification. | [References]
