    螺[异苯并呋喃-1(3H),4'-哌啶]的合成作为潜在的中枢神经系统药物。
    摘要:
    识别氨基烷基(芳基)异苯并呋喃部分可促进1'-甲基-3-苯基螺[异苯并呋喃-1(3H),4'-哌啶](7a,HP 365)和脱甲基类似物9a(HP 505)的合成抗抑郁药talopram(Lu 3-010)和trans-10,11-dihydro-5,10-epoxy-5- [3-(甲基氨基)丙基] -5H-dibenzo [a,d] cyclohepten-11-ol共有(MK-940)。通过2-溴二苯甲基甲基醚的锂化反应,然后添加1-甲基-4-哌啶酮和酸催化的环化反应,可以方便地合成7a。通过标准方法的N-脱烷基化得到9a。通过发现丁苯那嗪对前导化合物7a和9a引起的上睑明显抑制,刺激了类似物的合成。最佳的抗丁苯那嗪活性与3-苯基螺-[异苯并呋喃-1(3H),4'-哌啶]部分相关,其中氮为碱性。通过引入大的氮取代基或大于H的C-3取代基对该部分进行修饰,显着降低了抗丁苯那嗪的活性。研究

  • Sulfoxide ligand metal catalyzed oxidation of olefins

    The enantioselective synthesis of isochroman motifs has been accomplished via Pd(II)-catalyzed allylic C—H oxidation from terminal olefin precursors. Critical to the success of this goal was the development and utilization of a novel chiral aryl sulfoxide-oxazoline (ArSOX) ligand. The allylic C—H oxidation reaction proceeds with the broadest scope and highest levels asymmetric induction reported to date (avg. 92% ee, 13 examples ≥90% ee). Additionally, C(sp3)-N fragment coupling reaction between abundant terminal olefins and N-triflyl protected aliphatic and aromatic amines via Pd(II)/sulfoxide (SOX) catalyzed intermolecular allylic C—H amination is disclosed. A range of 52 allylic amines are furnished in good yields (avg. 76%) and excellent regio- and stereoselectivity (avg. >20:1 linear:branched, >20:1 E:Z). For the first time, a variety of singly activated aromatic and aliphatic nitrogen nucleophiles, including ones with stereochemical elements, can be used in fragment coupling stiochiometries for intermolecular C—H amination reactions.
    通过Pd(II)-催化的烯烃末端前体的烯丙基C—H氧化,已经实现了对异色烷基苯并环的对映选择性合成。这一目标的成功关键在于开发和利用一种新型手性芳基亚砜-噁唑啉(ArSOX)配体。烯丙基C—H氧化反应具有迄今报道的最广泛范围和最高水平的不对称诱导(平均92% ee,13个例子≥90% ee)。此外,通过Pd(II)/亚砜(SOX)催化的分子间烯丙基C—H胺化揭示了丰富的末端烯烃和N-三氟甲磺酰保护的脂肪族和芳香族胺之间的C(sp3)-N片段偶联反应。一系列52种烯丙基胺以良好的产率(平均76%)和优异的区域和立体选择性(平均>20:1线性:支链,>20:1 E:Z)提供。首次,各种单独活化的芳香族和脂肪族氮亲核试剂,包括具有立体化学元素的试剂,可以在分子间C—H胺化反应的片段偶联化学计量中使用。
