    他汀类手性侧链的合成——内酯与内酯途径
    摘要:
    4-O-受保护的 (4R,6S)-4-羟基-6-(羟基甲基)四氢吡喃-2-酮 (3) 衍生自对映异构纯 (3R,5S)-3-羟基-5,6-(异亚丙基二氧基)己酸酯(2) 通常被认为是合成具有药理意义的他汀类药物的关键中间体。值得注意的是,到目前为止,无法从文献中得出关于这一假设的证据。我们的研究表明,只有甲硅烷基类型的保护基团才能成功用于初始 (3R,5S)-3-羟基-5,6-(异亚丙基二氧基)己酸乙酯 (1) 的 3-O-保护。环化后,羟基内酯 3b 转化为甲苯磺酸酯 5b,依次转化为碘化物 6b。后者被转化为膦酸酯9b。通过甲苯磺酸盐 5b 的 X 射线结构分析证实了中间体的所有立体化学归属和非对映异构纯度。出奇,甲苯磺酸盐 5b 和碘化物 6b 都不能转化为相应的腈 7b,腈 7b 是制备阿托伐他汀的关键中间体。膦酸酯 9b 和醛 4b 是最接近氟伐他汀和瑞舒伐他汀内酯的中间体。不幸的是,膦酸酯

    Bakers' yeast oxidation of methyl para-tolylsuifide: Synthesis of a chiral intermediate in the preparation of the mevinic acid-type hypocholestemic agents
    摘要:
    The use of (R)-methyl para-tolylsulfoxide as a chiral auxiliary in a novel synthesis of a key intermediate en route to mevinic acid-type hypocholestemic agents is described. The synthesis is short and simple consisting of eight steps to yield enantiomerically pure beta-silyloxy-delta-lactone. The chiral sulfoxide used in the synthesis was obtained via a straightforward biooxidation of methyl paratolylsulfide using bakers' yeast (Saccharomyces cerevisiae NCYC 73). The biotransformation involves the use of whole cells and affords the sulfoxide in good yield and with high stereoselectivity.

    (salen)Al-catalyzed asymmetric conjugate addition of salicylaldoxime to α,β-unsaturated imides is the key step in an efficient and highly enantioselective two-step formal hydration of these electron-deficient olefins. This reaction constitutes the first example of an enantioselective conjugate addition of an oxygen-centered nucleophile to α,β-unsaturated carboxylic acid derivatives. Application of this method

    Statins are inhibitors of 3‐hydroxy‐3‐methyl‐glutaryl coenzyme A reductase (HMG‐CoA reductase) and became the standard of care for treatment of hypercholesterolemia because of their efficacy, safety, and long‐term benefits. They are administered as diastereo‐ and enantiomerically pure compounds. We summarize here two new approaches for the total synthesis of the most important representatives, atorvastatin
