实验步骤: Obtained from Intermediate 40 (1.0 g, 2.85 mmol) by the procedure described in Intermediate 2. Purification by column chromatography with silica gel and n-hexane/ethyl acetate (from 10:1 to 5:1) as eluent gave the title compound (0.68 g, 82%) as oil, Purification by column chromatography with silica gel and n-hexane/ethyl acetate (from 10:1 to 5:1) as eluent

实验步骤: Obtained from Intermediate 28 (9.5 g, 40 mmol) by the procedure described in Intermediate 2. The title compound was obtained (5.55 g, 80%) as oil.

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of Intermediate 2 (0.60 g, 3.22 mmol) in 1,6-dibromohexane (1.74 mL, 11.27 mmol) was added tetrabutylammonium bromide (21 mg, 0.064 mmol) and 50% sodium hydroxide (1.2 mL). The mixture was stirred at room temperature overnight. The crude reaction was diluted with n-hexane (20 mL), washed with water (2×10 mL), dried (Na2SO4), and the solvent removed under reduced pressure. The title compound was obtained (2.1 g, 52% purity) and was used in the next step without further purification. The crude reaction washed with water (2×10 mL) dried (Na2SO4) the solvent removed under reduced pressure
