The invention belongs to the field of medicinal chemistry, and relates to a preparation method and application of pongamol. The preparation method comprises the following steps: with 1,3-cyclohexanedione (6) as a starting raw material, carrying out a cyclization reaction to obtain 6,7-dihydro-4-(5H)-benzofuranone (7); carrying out acylation reaction on the compound (7) to obtain 5-acetyl-6,7-dihydro-4-(5H)-benzofuranone (8); carrying out dehydrogenation reaction on the compound (8) to obtain 1-(4-hydroxy-5-benzofuryl) ethyl ketone (3); carrying out methylation reaction on the compound (3) to obtain 1-(4-methoxy-5-benzofuryl) ethyl ketone (4); and condensing the compound (4) with benzoyl chloride to obtain the pongamol. According to the preparation method, the selected reagents are cheap and easy to obtain, the post-treatment method is simple, the reaction conditions are mild, and the product yield is high. Pharmacological activity experiments show that the synthesized compound has nerve injury resistance and anti-inflammatory activity, which means that the compound has a good application prospect in the field of treatment of nerve injury and inflammation related diseases.
