実験手順
To (±)-2-(tert-butoxycarbonylamino)-2-(thiophen-3-yl)propanoic acid (E4) in THF at 0° C. is added BH3-THF dropwise. The solution is allowed to warm to room temperature and stirred for an additional 2 hours. The solution is cooled to 0° C., quenched with AcOH (10%)/MeOH, and evaporated. Column chromatography (SiO2, EtOAc) gives pure tert-butyl 3-hydroxy-1-(thiophen-3-yl)propylcarbamate (E73A).
