Bridged helicenes: 3,15-ethano- and 3,15-(2-oxapropano)-[7]heliceneThe title compounds (35 and 33, see Scheme 4) have been synthesized from a common intermediate: 3,15-dimethoxycarbonyl-[7]helicene (26). The conformation of the bridged [7]helicenes (X-ray diffraction) and their 1H-NMR. spectra have been compared to the conformation and 1H-NMR. spectra of [7]helicene and 3,15-dimethyl-[7]helicene (10).
