The thermal reaction of a cyclopentadienone with 6,6′-dimethoxy-5,5′-binaphthoquinone gives, in a single step, a mol. ribbon consisting of two twisted aromatic systems fused to a heteropentahelicene e. g., I. Such mols. constitute a new class of chiral polycyclic aromatic compounds, the “hairpin furans”.
