专利号:WO-2025092475-A1 优先权日:2023-11-02 标题 :Synthesis method for bempedoic acid and bempedoic acid intermediate, and bempedoic acid intermediate 发明人:ZHAI NING; WANG GUOPING; ZHAO MIN; YU ZHENPENG; WANG SHIKANG 权利人:YANGZHOU AURISCO PHARMACEUTICAL CO LTD 摘要:The present invention provides a preparation method for bempedoic acid and a bempedoic acid intermediate, and a bempedoic acid intermediate. The preparation method comprises: taking a novel intermediate compound 6 as a raw material, and carrying out hydrolysis, removal of protecting groups on hydroxyl groups, and reduction to obtain bempedoic acid; and taking caprolactone as a starting material, carrying out self-condensation of caprolactone, and then carrying out ring opening, bromination, carbonyl protection, and α-alkylation to obtain the intermediate compound 6. The preparation method for bempedoic acid in the present invention is simple, convenient and safe to operate, high in yield, low in production cost, and easy for industrial production.
