Triacetoxyperiodinane → tert-Butyl-(2S,3R)-3-{[tert-butyl(dimethyl)silyl]oxy}-2-formylpyrrolidine-1-carboxylate

참여 물질

반응 단계

To (2R,3R)-3-(tert-Butyl-dimethyl-silanyloxy)-2-hydroxymethyl-pyrrolidine-1-carboxylic acid tert-butyl ester (51B) (6.70 g, 20.24 mmol) in CH2Cl2 (100 mL) at 0° C. was added Dess-Martin periodinane. The ice bath was removed and the reaction was warmed to rt. After 2 h, saturated aqueous Na2S2O3 and NaHCO3 (ca. 100 mL each) were added and the reaction mixture was stirred vigorously for 0.5 h. The layers were separated, the organic layer was washed with a mixture of saturated aqueous Na2S2O3 and NaHCO3 followed by brine, dried (MgSO4), and was then filtered and concentrated to obtain the title compound (7.20 g) as a yellow oil.
