制备方法与用途

用途

1-(4-氯吡啶)-2-乙酮作为一种芳香类杂环化合物,由于其官能团含有卤素和羰基,能够与其他化合物发生多种化学反应,如取代反应、亲和加成反应等。因此,它具有良好的化学活性,在医药领域中作为重要中间体。

制备

在氮气保护下,将4-氯-2-氰基吡啶(60g, 0.42mol)和四氢呋喃(1000ml)加入到一个2L三口瓶中并搅拌至溶解。冷却至0℃后,在约45分钟内缓慢滴加甲基碘化镁格氏试剂(200ml,3M的四氢呋喃溶液)。初期体系呈现为透明、深色的溶液,随后调整滴加速率,保持反应液温度在0-10℃之间。当所有格氏试剂加入后,在0℃下搅拌反应2小时。接着将反应混合物加入到1500ml冰水中,并使用2mol/L盐酸调节pH值至2。继续搅拌15分钟后静置分液,水相用乙酸乙酯萃取直至TLC检测无产物。合并有机相后,用饱和氯化钠水溶液洗涤一次,并用无水Na2SO4干燥。通过旋转蒸发器在减压条件下除去所有溶剂,得到66g黄棕色油状粗产物。

粗产物经过柱色谱法纯化,合并合适的级分(通过TLC分析表征)。最终去除溶剂后,得到1-(4-氯吡啶)-2-乙酮51g(0.32mol),产率为76%,为透明深色油状物。

    Biocatalytic preparation of optically active 4-(N,N-dimethylamino)pyridines for application in chemical asymmetric catalysis
    摘要:
    4-Chloro-2-(1-hydroxybenzyl)pyridine and 4-chloro-2-(1-hydroxyalkyl)pyridines were obtained with moderate to excellent enantiomeric excesses and high isolated yields by bioreduction with Baker's yeast of the corresponding ketones. The resulting optically active alcohols were transformed into adequate DMAP derivatives, which have been applied in asymmetric catalytic processes as nucleophilic catalysts in the stereoselective chemical alkoxycarbonylation of 1-phenylethanol or as chiral ligands in the enantioselective addition of diethylzinc to benzaldehyde.
