(1R,2R)-1-(2,4-bis(benzyloxy)-6-chloro-5-phenylpyridin-3-yl)-2-methylbut-3-en-1-ol 6 To a stirred mixture of potassium tert-butoxide (67 mg, 0.55 mmol, 1.2 equiv, dried at 80 °C/0.5 mm for 8 h) in THF (0.55 mL) and trans-2-butene (0.1 mL, 1.15 mmol, 2.5 equiv) was added n-butyllithium (2.5 M in hexane, 0.22 mL, 0.55 mmol, 1.2 equiv) at -78 °C. The reaction mixture was stirred at -45 °C for 10 min and was subsequently cooled down to -78 °C. (+)-Methoxydiisopinocamphenylborane (1 M in ether, 0.7 mL, 0.70 mmol, 1.5 equiv) was added and the mixture was stirred at -78 °C for 30 min. Boron trifluoride etherate (0.1 mL, 0.80 mmol, 1.7 equiv) was added dropwise. A solution of the aldehyde 5 (200 mg, 0.46 mmol, 1 equiv) in THF (0.46 mL) was then added with a syringe pump (flow rate 5 mL/h) at -78 °C. The mixture was stirred at this temperature for 4 h, treated with 0.40 mL of 3 N NaOH and 0.16 mL of 30% H2O2, and refluxed for 1 h. The aqueous layer was extracted with dichloromethane. The organic layer was washed with water and brine, and dried over magnesium sulfate. The solvent was removed under reduced pressure and the crude mixture was purified by flash column chromatography (EtOAc/petroleum ether 10:90) to furnish the expected alcohol 6 as a yellow oil (51 mg, 23%).
