Application:
Boc-L-Threonine (Boc-Thr-OH) (CAS: 2592-18-9), amino acids and derivatives, peptide synthesis, organic synthesis intermediate, pharmaceutical intermediates, biochemical reagents. Boc-L-Threonine is mainly used in polypeptide synthesis, mainly used in a variety of drugs and biotechnology applications. Threonine has a wide range of uses and functions. In the prior art, Boc is used as a protecting group to protect L-Threonine. Boc-L-Threonine is an important intermediate raw material for many kinds of medicine and biotechnology. Preparation 1. add 15.8gL-threonine, add 200ml of 0.0005mol/L potassium bicarbonate solution, stir and dissolve, then add 8g of (Boc)2O for reaction for 2 hours, then add 8g of (Boc)2O for reaction for 2 hours, and finally add 9g of (Boc)2O for reaction for 2 hours. 2. After adjusting PH = 3 with 0.001mol/L hydrochloric acid, use tert-butyl acetate 0.4L/time to extract the product three times. Combine ester layers and wash with brine to neutral. Add 15 grams of anhydrous sodium sulfate and dry for 8 hours. 3. Filter, concentrate and dry the filtrate under reduced pressure, add 50ml petroleum ether, stir and crystallize. Centrifuge out the product and dry it. The product 22.4g is obtained. The yield is 91.73%.
