2-氨基-3,3,3-三氟丙醇

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

实验步骤: To a stirred solution of (S)-tert-butyl (1-oxopropan-2-yl)carbamate (3.15 g, 18.18 mmol), and DCM (91 ml) was added 2-amino-3,3,3-trifluoropropan-1-ol (2.230 g, 17.28 mmol). Stirred at ambient temperature for 10 minutes and then added sodium triacetoxyborohydride (5.78 g, 27.3 mmol). The mixture was stirred overnight. The reaction was diluted with DCM and then washed with 1 N NaOH, brine dried over MgSO4, filtered and the solvent removed to provide 4.0 grams of tert-butyl ((2S)-1-((1,1,1-trifluoro-3-hydroxypropan-2-yl)amino)propan-2-yl)carbamate as a colorless oil that was used without further purification. LRMS m/z (M+H)+ 287.3 found, 287.3 required. The mixture was stirred overnight washed with 1 N NaOH, brine dried over MgSO4 filtered the solvent removed
