Reaction Steps

As shown in Reaction 1, first, magnesium was added to 2-(5-bromo-2,3-dimethoxyphenyl)-1,3-dioxane as a starting material, which substituted an aldehyde group with an acetyl group. Then, Compound (III) derivative was substituted thereto to synthesize (3-(1,3-dioxan-2-yl)-4,5-dimethoxyphenyl)(5-(furan-2-yl)-2-methoxyphenyl)methanol. Thus obtained (3-(1,3-dioxan-2-yl)-4,5-dimethoxyphenyl)(5-(furan-2-yl)-2-methoxyphenyl)methanol (1.7 g, 4.0 mmol) was dissolved in 40 ml of anhydrous dichloromethane, whereto 4 Å molecular sieves (0.6 g) and pyridinium dichromate (PDC) (2.24 g, 6.0 mmol) were added sequentially at 0° C. The mixture was reacted at room temperature for 24 hours. After completion of the reaction, diethylether (150 ml) was added to the reaction mixture, and the precipitates were filtered off using Celite. An organic layer was extracted out from the filtrate using brine, and the organic layer was dried over Na2 SO3. The solvent was removed, and the resulting residue was purified by column chromatography (SiO2, n-Hex/EA=1/1) to synthesize Compound 233 (1.02 g, 60%).
