Synthesis method of resveratrol

The invention provides a synthesis method of resveratrol.The method includes the steps of dissolving 3,5-dihydroxybenzoic acid in solvent, conducting reaction on sodium borohydride and Lewis acid to obtain 3,5-dihydroxy-benzyl alcohol, conducting reaction on 3,5-dihydroxy-benzyl alcohol and triphenylphosphine hydrobromic acid in certain solvent to obtain corresponding phosphonium, and making the obtained phosphonium react with p-hydroxy benzaldehyde under the effect of strong alkali to directly obtain the product resveratrol.The preparation method includes few steps, precious metal catalysts are prevented from being used in protection and deprotection processes of phenolic hydroxyl groups in the technology, cost is low, operation is easy, reaction conditions are easy to achieve, and industrial production is facilitated.
