tert-butyl N-(2-hydroxy-3-phenylpropyl)carbamate

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 (2-hydroxy-3-phenylpropyl)carbamate (10.0 g, 39.8 mmol), PPh3 (12.5 g, 47.8 mmol) and phthalimide (6.44 g, 43.8 mmol) in THF (125 mL) at RT was added DEAD (9.4 mL, 59.7 mmol) over 5 min. After 1 h at RT, the reaction solution was concentrated and purified on silica (hexanes/EtOAc, 2:1) to give the title compound as a white solid (12.6 g, 83%): LCMS (ES) m/z 381 (M+H)+. the reaction solution was concentrated purified on silica (hexanes/EtOAc, 2:1)
