    • PURPOSE: Provided is a preparation method of simvastatin, which has excellent inhibition activity of HMG-CoA reductase and is thus useful as a therapeutic agent for Hyperlipemia, in high yields. CONSTITUTION: A preparation method of simvastatin comprises the steps of: preparing diol lactone of the formula(III) by deacylation of a lovastatin of the formula(II) in the presence of phase transfer catalyst then followed by heat-refluxing; reacting secondary alcohol at pyranone ring of diol lactone with 2,3-dihydro-2H-pyrane in the presence of acid-catalyst to prepare 4-THP-diol lactone of the formula(IV) containing a tetrahydropyranyl group; coupling 4-THP-diol lactone with 2,2-dimethylbutylchloride to prepare 4-THP-simvastatin of the formula(V); and removing the tetrahydropyranyl group from 4-THP-simvastatin in the presence of acid catalyst.
    • 目的:提供辛伐他汀的制备方法,其具有优异的HMG-CoA还原酶抑制活性,因此可用作高脂血症的治疗剂。 构成:辛伐他汀的制备方法包括以下步骤:在相转移催化剂存在下,通过使式(II)的洛伐他汀脱酰化然后加热回流来制备式(III)的二醇内酯; 在酸催化剂存在下,使二醇内酯的吡喃酮与二氢-2H-吡喃的仲醇反应制备含有四氢吡喃基的式(Ⅳ)的4-THP-二醇内酯; 将4-THP-二醇内酯与2,2-二甲基丁基氯反应制备式(V)的4-THP-辛伐他汀; 并在酸催化剂存在下从4-THP-辛伐他汀中除去四氢吡喃基。
