Properties | Boc-L-2-aminobutyric acid ((2S)-2-[(2-methylpropan-2-yl)oxycarbonylamino]butanoic acid), also known as L-2-(tert-butoxycarbonylamino) butyric acid, its molecular formula is C9H17NO4, molecular weight is 203.24,CAS number is 34306-42-8, melting point 70-74°C, and white powder at room temperature. |
synthesis | Boc-L-2-aminobutyric acid is generally synthesized from DL-2-aminobutyric acid. the specific synthesis steps are as follows: dissolve 10.3g of DL-2-aminobutyric acid in a mixed solution of 95m L 1M NaOH solution and 65mL of methanol, add 27.5mL of ditert-butyl dicarbonate (I. e. Boc anhydride, 1.2 eq.) into an ice bath, slowly raise to room temperature, and stir for 12 hours. After the reaction is over, methanol is removed by spin evaporation, pH is adjusted to 1-2 for 1M hydrochloric acid, ethyl acetate extraction (50 mLx3), saturated salt water washing (40 mLx2), anhydrous sodium sulfate water removal, and finally spin evaporation to obtain 18.9g colorless solid (93.4%). |
