Oxyresveratrol synthesis method

The invention provides an oxyresveratrol synthesis method which comprises the following steps: firstly performing a reflux reaction between raw materials 3,5-dimethoxybenzyl alcohol and phosphorus oxychloride; after the reaction is complete, pressurizing and recycling the solvent; filtering, washing to neutrality and drying to obtain 3,5-dimethoxybenzyl chloride; performing a reflux reaction between the obtained 3,5-dimethoxybenzyl chloride and trimethyl phosphite in a solvent DMF (dimethyl formamide); after the reaction is complete, adding a catalyst sodium methylate solution, and adding a mixed solution of 2,4-dimethoxy benzaldehyde and DMF to obtain tetramethoxy diphenyl ethylene; and finally, performing a reflux reaction between the obtained tetramethoxy diphenyl ethylene and aluminum trichloride and xylene, wherein oxyresveratrol is obtained after the reaction is complete. According to the method provided by the invention, a Witting-Homer reaction is adopted, the raw materials are easily available, the yield is high, the cost is low, and the method is suitable for industrial production.
