Sodium borohydride → tert-butyl (2S,4R)-4-((tert-butyldimethylsilyl)oxy)-2-(hydroxymethyl)pyrrolidine-1-carboxylate

참여 물질

반응 단계

Sodium borohydride (227 mg, 6 mmol) was added at 0° C. to a stirred solution of (2S,4R)-N-BOC-4-(t-butyldimethylsilyloxy)prolinaldehyde (522 mg, 1.58 mmol) in MeOH (10 mL), and the mixture was stirred at rt for 3 h. The reaction was quenched by adding sat. NaHCO3 (20 mL), and the resulting mixture was extracted with EtOAc (3×50 mL). The EtOAc extracts were washed with brine (2×50 mL), and dried (Na2SO4). The solvent was removed in vacuo to give (2S,4R)-N-BOC-4-(t-butyldimethylsilylhydroxy)prolinol (550 mg).
