実験手順

To a solution of cuprous iodide (0.14 g, 0.74 mmol) in tetrahydrofuran (2 ml) was added phenylmagnesium bromide in tetrahydrofuran (1M, 2.22 ml, 2.22 mmol) dropwise at −40° C. After 5 minutes 3-(4-methoxyphenyl)-7-(oxiran-2-ylmethoxy)chromen-4-one (0.24 g, 0.74 mmol) in tetrahydrofuran (4 ml) was added slowly, and stirred at −40° C. for 1 hour. The mixture was quenched with saturated ammonium chloride and water, extracted with ethyl acetate, the organic layer washed with brine, dried over sodium sulfate, and the solvent removed under reduced pressure. The residue was purified by preparative thin layer chromatography, eluting with 10% methanol/methylene chloride, followed by ethyl acetate/hexane 2/3, to provide 7-(2-hydroxy-3-phenylpropoxy)-3-(4-methoxyphenyl)chromen-4-one.
