boc-L-4-溴苯丙氨醇

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of 1,1-dimethylethyl [(1S)-2-(4-bromophenyl)-1-(hydroxymethyl)ethyl]carbamate (70.6 mmol), tripheylphosphine (84.7 mmol), and phthalimide (84.7 mmol) in anhydrous tetrahydrofuran (550 mL) at 0° C. was added dropwise duisopropyl azodicarboxylate (84.7 mmol) over 10 minutes. The reaction continued to stir allowing to warmn to RT over 5 h. The reaction was then concentrated in vacuo and product was triturated out of solution using ethyl acetate (500 mL). The precipitate was filtered, washed with ethyl acetate (3×100 mL), and dried to afford the title product as a white solid (57%). ESMS [M+H]+: 460.4. The reaction was then concentrated in vacuo and product was triturated out of solution The precipitate was filtered washed with ethyl acetate (3×100 mL) dried

实验步骤: To a solution of 4-bromo-N-{[(1,1-dimethylethyl)oxy]carbonyl}-L-phenylalanine (72.6 mmol), in anhydrous diethyl ether (550 mL) at 0° C. was added slowly lithium aluminum hydride, 95% (108.9 mmol). The resulting solution was stirred for an additional 2 h at 0° C. The reaction was then carefully quenched with a saturated aqueous solution of sodium bicarbonate (73 mL) which stirred at RT for half an hour. Lithium aluminium salts crashed out of solution and were removed by filtration. The filtrate was concentrated and vacuum pumped for 24 h to afford the title product as a white solid (97%). ESMS [M+H]+: 331.2. The reaction was then carefully quenched with a saturated aqueous solution of sodium bicarbonate (73 mL) which stirred at RT for half an hour were removed by filtration The filtrate was concentrated vacuum pumped for 24 h
