The enantioselective synthesis of azahelicenes and S-shaped double azahelicenes has been achieved via the Au-catalyzed sequential intramolecularhydroarylation of alkynes. The use of excess AgOTf toward a Au(I) complex is crucial for this transformation. Interestingly, the circularly polarized luminescence activity of the S-shaped double azahelicenes was significantly higher than that of the azahelicenes
氮杂螺旋烯和 S 型双氮杂螺旋烯的对映选择性合成是通过 Au 催化的炔烃的顺序分子内加氢芳基化实现的。对 Au(I) 复合物使用过量的 AgOTf 对这种转变至关重要。有趣的是,S形双氮杂螺旋烯的圆偏振发光活性明显高于氮杂螺旋烯。
