PROCEDURE
实验过程
The above allyl alcohol (238 mg, 0.0.65 mmol), methyl (4-hydroxy-2-methylphenoxy)acetate (140 mg, 0.715 mmol; example 2) and triphenylphosphine (205 mg, 0.78 mmol) were dissolved in a mixture of anhydrous toluene (8 mL) and tetrahydrofuran (6 mL). The mixture was cooled to 0° C., kept under argon and a degassed solution of diisopropyl azodicarboxylate (0.163 mL, 0.78 mmol) in anhydrous tetrahydrofuran (1 mL) was added dropwise during 10 min. The reaction mixture was allowed to warm up to ambient temperature with the bath and then was stirred for 3 days. The solvents were evaporated in vacuo and the residue was submitted to flash column chromatography (silica gel Fluka 60, hexanes/ethyl acetate 85:15) affording methyl (E)-[4-[3-(4-iodophenyl)-3-(6-phenylpyridin-3-yl)allyloxy]-2-methylphenoxy]acetate as oil.
