CBZ-D-缬氨酸 - Reference Information
| Application | N-benzyloxycarbonyl-D-valine is an amino acid derivative, which can be obtained by the reaction of D-valine and benzyl chloroformate, The base can be selected from sodium bicarbonate and sodium hydroxide. |
| preparation | at 0 ℃, dissolve 10mmolD-valine in 50ml of sodium bicarbonate (NaHCO3) saturated solution at this temperature to obtain the dissolved liquid. while stirring, add 11mmol of benzyl chloroformate to the dissolved liquid at a speed of 1 drop/10 seconds for reaction. after dropping , place it at 30 ℃, stir and react for 15 hours, do thin-layer detection, and after the solution is completely reacted, wash with 50ml/time of ether for 3 times, discard the ether, and get the aqueous phase. The aqueous phase is adjusted to PH with concentrated hydrochloric acid with a mass concentration of 30% to 3, milky white solid appears, and the liquid after milky white solid appears is extracted with 50ml/time of ethyl acetate for 3 times, and merged, the combined liquid is washed twice with 50ml/ distilled water twice and once with 50ml saturated salt water, then dried with anhydrous magnesium sulfate for 7 hours, filtered, and the filtrate is concentrated under reduced pressure to obtain a light yellow oil. The mixed solvent prepared by ethyl acetate and petroleum ether with a volume ratio of 1:3 is used as the mobile phase, and purified through a chromatography column to obtain N-benzyloxycarbonyl D-valine, it is a colorless and transparent oil with a yield of 68.7%. |
