    • Preparation of (R)-3-(2-Bromo-3-phenyl-acryloyl, 5,5-dimethyl-4-phenyl-oxazolidin-2-one 3. To a solution of 2 (6.42 g, 20.0 mmol) in CHCl3 (60 mL) was added dropwise of Br2 (1.5 mL, 26 mmol) dissolved in CHCl3 (15 mL, The resulting mixture was stirred at room temperature and rapidly (3 h) discolorated. After evaporation of the solvent and unreacted Br2 in vacuo, the oily residue was dissolved again in CHCl3 (50 mL, To this solution was added dropwise of Et3N (5 g, 2.5 mol eq) and the resulting reaction mixture was stirred (3 h) till completion (judged by TLC, The cooled reaction mixture was diluted with CHCl3 and washed successively with 0.1 N HCl, sat. NaHCO3sol n, brine, and dried (MgSO4, Evaporation of the solvent gave the crude product. The product was recrystallized from petroleum ether/ethyl acetate 3:2 to give the title compound 3 (6.86 g, 17.2 mmol) as a
