95% | The procedure was adapted from the method of Comins et al ' N-methylpiperazine (670 mu, 6.6 mmol, 1.1 equiv) was dissolved in 20 mL THF and cooled to -20 °C. -Butyllithium (2.4 M, 2.65 mL, 6.3 mmol, 1.05 equiv) was added in a dropwise fashion, resulting in an orange solution. The solution was stirred at this temperature 15 min before a solution of 3,5- dimethoxybenzaldehyde (SI, 1.00 g, 6.0 mmol, 1 equiv) in 3 mL THF was added in a dropwise fashion, causing a color change to yellow. The solution was stirred at this temperature 30 min before a second portion of ft-butyllithium (2.4 M, 7.5 mL, 18.1 mmol, 3 equiv) was added in a dropwise fashion. At this the flask was stored in a -20 °C freezer for 24 h. The flask was re-submerged in a -20 °C bath, and freshly distilled methyl iodide (2.25 mL, 36.1 mmol, 6 equiv) was added in a dropwise fashion, resulting in a mild exotherm. The solution was stirred 30 min at -20 °C and was removed from its bath, warming to room temperature. After 30 min the reaction was quenched by the addition of 20 mL 0.5 M HC1, and the solution was stirred 30 min without a cap. The layers were separated and the aqueous phase was saturated with sodium chloride. The aqueous phase was extracted with Et^O, dried over MgS04 and concentrated. The product was purified by column chromatography (10percent EtO Ac/hex). Colorless solid, 1.03 g, 5.72 mmol, 95percent yield. NMR spectra were identical to the previously reported compound.2 NMR (400 MHz, CDCl3) delta 9.88 (s, 1H), 7.03 (s, 2H), 3.87 (s, 6H), 2.14 (s, 3H); 13C NMR (101 MHz, CDCl3) delta 192.0, 158.7, 135.1, 122.5, 104.7, 55.9, 9.0. |

Example 13; (4S)-4-benzyl-3-{(2R)-2-[(S)-(3,5-dimethoxy-4-methylphenyl)(hydroxy)methyl]-5-phenylpentanoyl }-1,3-oxazolidin-2-one: To an ethyl acetate (18 ml) solution, the compound (6.13g) produced in Example 12 and <strong>[1011-27-4]3,5-dimethoxy-4-methylbenzaldehyde</strong> (3.60 g), triethylamine (5.07ml), trimethylsilyl chloride (3.47 ml) and magnesium chloride (347 mg) were added, and the mixture was stirred at room temperature overnight. Water was added to the reaction mixture, followed by extraction with ethyl acetate. The extract was washed with brine, dried over anhydrous sodium sulfate, and concentrated. The residue was dissolved in methanol (18 ml), and 1N hydrochloric acid (1.8 ml) was added thereto. The reaction mixture was stirred at room temperature for 5 mintues, and concetrated. The residue was purified with silica gel column chromatography (hexane:ethyl acetate = 49:1 --> 19:1 --> 9:1 --> 4:1) to give the title compound (8.24 g) having the following physical properties. TLC: Rf 0.61 (hexane: ethyl acetate = 2:1); 1HNMR: delta 1.58 (m, 2H), 1.86 (m, 1H), 2.08 (s, 3H), 2.49 (dd, 1H), 2.57 (t, 2H), 3.09 (dd, 1H), 3.20 (d, 1H), 3.82 (s, 6H), 4.10 (m, 2H), 4.62 (m, 2H), 4.80 (m, 1H), 6.63 (s, 2H), 7.19 (m, 10H). |
