PROCEDURE

实验过程

Place under argon a suspension of n-hexyltriphenylphosphonium bromide (0.420 g, 1 mmol) in 10 mL of dry THF. Add potassium tert-butoxide (0.112 g, 1 mmol). Stir the mixture for 1 h. Add a solution of (R)-2-[(4S,5S)-3-Acetyl-4-(3,5-difluoro-benzyl)-2,2-dimethyl-oxazolidin-5-yl]-4-oxo-pyrrolidine-1-carboxylic acid tert-butyl ester (0.045 g, 0.1 mmol) in 5 mL of dry THF. Stir the mixture overnight. Add water, extract with diethyl ether, dry over MgSO4, concentrate under reduced pressure and purify (silica gel chromatography, eluting with ethyl ether:hexane mixtures) to give the title compound (0.04 g, 76%).
