  通过联苯的区域选择性 CC 键活化催化对映选择性合成轴向手性多环芳烃 (PAH)

  摘要：

  手性多环芳烃 (PAHs) 由于其手性和极度扩展的 π 共轭体系，有望具有不寻常的物理性质。事实上，多环芳烃有望用作手性识别剂和有机半导体。因此，强烈需要一种合成手性多环芳烃的方法。尽管有一些关于螺旋手性多环芳烃的对映选择性合成的报道，但以对映选择性的方式合成轴向手性多环芳烃仍然很困难。在此，我们报告了通过区域选择性裂解联苯的空间位阻 CC 键，催化对映选择性合成苯并 [b] 荧蒽基轴向手性多环芳烃的产率和对映选择性（高达 >99%，>99% ee）。该反应可用于连续环化以合成具有两个手性轴的多环多环芳烃。获得的手性多环芳烃具有高ε值（高达ε=8.9×104）、量子产率（高达Φ=0.67）和圆偏振发光（CPL）特性（|glum|=3.5×10-3）。
