    描述:
    5-hydroxy-7-methyloctan-3-one盐酸 作用下, 以 为溶剂, 以18.0 g的产率得到(E)-7-Methyl-4-octen-3-one

    一种区域选择性醛醇缩合的新方案,可替代地方便地合成β-酮醇和α,β-不饱和酮。
    摘要:
    通过在水性介质中将β-酮酸与醛进行Knoevenagel缩合,可以实现β-酮醇和α,β-烯酮的常规合成。用10%的KOH水溶液将β-酮酸酯皂化,得到β-酮酸的钾盐,将其与醛在pH值为7.8-8.0的条件下于60摄氏度下原位缩合5-6小时。中间体β-酮羧酸酯在反应介质中平滑脱羧,从而以高收率(75-90%)得到β-酮醇。将反应混合物在pH 1下酸化并在剧烈搅拌下于70°C加热6小时,可直接生成相应的α,β-不饱和酮,收率良好(65-75%)。
