(b) Alkylation with allyl iodide: To a solution of lithium diisopropylamide (23 mL, 46 mmol; 2 M in THF) in anhydrous THF (120 mL), stirred at -78 C under argon, a solution of (S)-4-benzyl-3-(3-methylbutanoyl)oxazolidin-2-one (10.0 g, 38.27 mmol) in anhydrous THF (10 mL) was added and the mixture was stirred for 1.5 h. To the resulting mixture allyl iodide (10.30 g, 61.32 mmol) was added dropwise and stirring was continued for another 30 min. The resulting mixture was warmed to -45 C at which it was stirred for 15 h. The reaction was quenched by the addition of 1 M aqueous HCl solution (100 mL) and the product was extracted with ethyl acetate (3 ¡Á 250 mL). The combined organic layers were successively washed with ice-cold 1 M aqueous HCl solution (100 mL), saturated aqueous Na-HCO3 solution (2 ¡Á 100 mL), and brine (2 ¡Á 100 mL), and dried over anhydrous Na2SO4. After removal of the solvents under reduced pressure 11.952 g of crude product were obtained which were further purified by radial chromatography on silica gel (petrolether/ethyl acetate = 10:1) to afford 8.302 g (72%) of alkylation product as a colourless oil. 1H NMR (300 MHz, CDCl3) delta: 0.98 (d, 6H), 1.98 (m, 1H), 2.35-2.54 (m, 2H), 2.64 (dd, 1H), 3.31 (dd, 1H), 3.83-3.90 (sym m, 1H), 4.12-4.17 (m), 4.65-4.73 (m, 1H), 5.02 (d, 1H), 5.09 (ddt 1H), 5.76-5.90 (m, 1H), 7.22-7.36 (m, 5H).
