Reaction Conditions

Reaction Steps

The above allyl alcohol (0.98 g, 2.60 mmol), methyl (4-hydroxy-2-methylphenoxy)acetate (0.545 g, 2.78 mmol; compound VÚFB-21004) and triphenylphosphine (0.782 g, 2.98 mmol) were dissolved in a mixture of anhydrous toluene (12 mL) and tetrahydrofuran (4 mL). The mixture was cooled to 0° C., kept under nitrogen and a degassed solution of diisopropyl azodicarboxylate (0.587 mL, 2.98 mmol) in anhydrous tetrahydrofuran (5 mL) was added dropwise. The reaction mixture was allowed to warm up to ambient temperature and then was stirred over night. The solvents were evaporated in vacuo and the residue was submitted to flash column chromatography (silica gel Fluka 60, hexanes/ethyl acetate 8:1) affording methyl (Z)-[4-[3-(4-cyclopropylphenyl)-3-(4-iodophenyl)allyloxy]-2-methylphenoxy]-acetate as solid mass.
