    共轭三取代烯酮的高度对映选择性铱催化加氢
    摘要:
    共轭烯酮的不对称氢化是制备光学活性酮的最有效,最直接的方法之一。在这项研究中,手性双齿Ir-N,P络合物被用于进入这些支架,以获得在α和β位置均具有立体中心的酮。获得了高达99%的出色的对映体过量,并具有良好或较高的分离产率。具有挑战性的二烷基取代的底物(很难通过令人满意的手性诱导进行氢化)以高度对映选择性的方式氢化。

    β-内酯是否参与碳基烯化反应?
    摘要:
    杂原子烯化试剂(如有机膦酸酯、磺酸酯等)用于将羰基化合物转化为烯烃,其作用机制涉及羟醛型加成、环化和四元环中间体的断裂。我们开发了一种使用 1,1,1,3,3,3-六氟异丙基甲基丙二酸乙酯的类似工艺,可将亲电芳基醛转化为 α-甲基肉桂酸酯,产率高达 70%。该反应似乎是通过形成β-内酯进行的,β-内酯在反应条件下自发脱羧。结果揭示了克诺文格尔-多布纳烯化反应,通常考虑羟醛型加合物的脱羧反断裂。
