At the same time, in a seperate flask charged with a solution of (S)-(+)-4-phenyl-2-oxazolidinone (8.86 g, 54 mmol) in anhydrous tetrahydrofuran (130 mL) under nitrogen at -78 C. was added dropwise a solution of n-butyl lithium (22 mL, 54 mmol, 2.5 M in hexanes). The mixture was stirred at -78 C. for 20 minutes and then transferred via a cannula into the reaction flask containing the mixed anhydride at -78 C. The reaction mixture was stirred at 0 C. for 1 hour, then warmed to room temperature and stirred for 18 hours. The mixture was quenched with saturated aqueous ammonium chloride solution (200 mL), concentrated to about half of its original volume under reduced pressure to remove tetrahydrofuran. The remaining mixture was extracted with ethyl acetate (2*250 mL). The organic layer was separated, combined, dried over sodium sulfate and concentrated under reduced pressure. The residue was purified by chromatography over silica gel eluted with 2:1 ethyl acetate/hexanes to give (S)-3-((E)-pent-2-enoyl)-4-phenyl-oxazolidin-2-one as a white foam (9.9 g, 75%)., 99395-88-7
99395-88-7 (S)-4-Phenyloxazolidin-2-one 730424, aoxazolidine compound, is more and more widely used in various fields.
