由于两端具有螺旋桨状顺式构象的叔苯三苯胺部分的预组织成分，以高产率合成了具有大环芳香酰胺结构的三螺旋结构。螺旋度源自每个 N-苯环之间的倾斜 T 形芳香族-芳香族 (CH-pi) 相互作用。 【结构：见正文】
A triple helicate, having a macrocyclic aromatic amide structure, was synthesized in high yield because of a preorganized component of the tertiary benzenetrianilide moieties in a propeller-like syn conformation at both ends. The helicity was derived from tilted T-shaped aromatic-aromatic (CH-pi) interactions between each of the N-phenyl rings. [structure: see text]
