A series of aza[4]helicenes have been conveniently synthesized in yields of 71–92 % by a one-pot procedure involving the Pictet–Spengler reaction. The structures of the aza[4]helicenes were characterized by 1H and 13C NMR spectroscopy, mass spectrometry, and X-ray crystallography. Moreover, it was found that the aza[4]helicenes self-assemble into 2D layers or herringbone-like structures in the solid
通过涉及 Pictet-Spengler 反应的单锅程序,已经方便地合成了一系列氮杂 [4] 螺旋烯,产率为 71-92%。氮杂[4]螺旋烯的结构通过1H和13C NMR光谱、质谱和X射线晶体学表征。此外,发现氮杂[4]螺旋烯在固态下自组装成二维层或人字形结构。此外,通过紫外和荧光光谱方法研究了光学性质。
