boc-4-nitro-L-phenylalanine - Reference Information
| Uses | BOC-L-4-nitrophenylalanine is a beige solid powder at room temperature and pressure. It is mainly used as an intermediate in organic synthesis and pharmaceutical chemistry. It can also be used to synthesize polypeptide drugs. |
| synthesis method | to (S)-4-nitrophenylalanine (2.00g,9.51mmol) in 2M sodium hydroxide aqueous solution (10mL) and tetrahydrofuran (5mL) mixed solution, adding di-tert-butyl dicarbonate (2.00g,9.17mmol), stirring at ambient temperature for 1 hour, the reaction mixture was diluted with H2O(25mL) and 1M hydrochloric acid (25mL), extracted with ether (3 x 25mL), the combined ether layer was washed with saline (1 x 25mL), the separated organic layer was dried with anhydrous magnesium sulfate, the magnesium sulfate solid was filtered out, and the obtained filtrate was concentrated under reduced pressure to obtain the target product BOC-L-4-nitrophenylalanine with a yield of 2.51g and 88%. |
