실험 절차

The above allyl alcohol (420 mg, 1.2 mmol), methyl (4-hydroxy-2-methylphenoxy)acetate (0.259 mg, 1.32 mmol; example 2) and triphenylphosphine (378 mg, 1.44 mmol) were dissolved in a mixture of anhydrous toluene (20 mL) and tetrahydrofuran (7 mL). The solution was cooled to 0° C., kept under nitrogen and a degassed solution of diisopropyl azodicarboxylate (0.28 mL, 1.44 mmol) in anhydrous tetrahydrofuran (2.5 mL) was added dropwise over 10 min. The reaction mixture was allowed to warm up to the ambient temperature with the bath and then was stirred for 48 h. The solvents were evaporated in vacuo and the residue was submitted to flash column chromatography (silica gel Fluka 60, hexanes/ethyl acetate 4:1) affording methyl (Z)-[4-[3-(4-iodophenyl)-3-(4-methylphenyl)allyloxy]-2-methylphenoxy]acetate as solidifying yellow oil.
