Stereospecific Winding of Polycyclic Aromatic Hydrocarbons into Trinacria Propellers

The synthesis of molecular propellers featuring low-energy activation barriers of the racemization reaction remains elusive. The trimerization reaction of enantiomerically-pure binaphthols with hexakis(bromomethyl)benzene enabled the one-step preparation of enantiomerically-pure molecular propellers, in which three binaphthyl rings are held together through dioxecine rings. X-ray diffraction analysis revealed that the six naphthyl moieties adopt a folded conformation, which shows a striking similarity to the mythological Sicilian symbol of Trinacria.
