  通过4-表位-J素B的结构-活性关系研究鉴定鞘氨醇激酶1和2的选择性抑制剂。

  摘要：

  最近，我们报道了4-epi-jaspine B对鞘氨醇激酶（SphKs）表现出强大的抑制活性。在这项研究中，我们使用基于后期交叉复分解反应的面向多样性的合成方法，研究了修饰2-表山s B的2-烷基基团以及THF环上官能团的作用。在大多数情况下，将对亚苯基系链引入烷基是有利的，而用氧原子取代碳原子会导致抑制活性的降低。此外，在末端引入大分子烷基导致该系列对SphKs的抑制活性与4-eps-jaspine B相比略有增加（化合物13对SphK1和SphK2的Q值分别为0.2和0.4，分别）。根据这项研究，我们确定了两种同工型选择性抑制剂，包括间亚苯基衍生物4 [IC50（SphK1）≥30μM；IC50（SphK2）=2.2μM]和甲基醚衍生物22 [IC50（SphK1）=4.0μM; IC50（SphK2）≥30μM]。

  螯合辅助的Rh（I）催化的芳香族酮亚胺或酮与烯烃的邻烷基化。

  摘要：

  本文描述的是芳族酮亚胺或酮与烯烃的Rh（I）催化的邻烷基化。该方法对包括烯烃烯丙基质子，α，ω-二烯和内烯烃的1-烯烃在内的各种烯烃显示出高反应活性和对单烷基化的选择性。为了进行机理研究，进行了H / D交换实验，结果表明，即使在45°C的低温下，邻位CH键也很容易断裂。该反应的关键步骤是形成稳定的五元链通过螯合辅助邻位CH键活化的金属环。此外，通过添加50mol％的苄胺作为螯合辅助工具，成功实现了Rh（I）配合物与芳族酮的直接邻烷基化。
