Front Cover: Stereospecific Winding of Polycyclic Aromatic Hydrocarbons into Trinacria Propellers (Chem. Eur. J. 61/2017).

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.
