The enantioselective synthesis of completely ortho-fused [9]- and [11]helicene-like mols. was achieved through a Rh-mediated, intramol., double [2+2+2] cycloaddn. of phenol- or 2-naphthol-linked hexaynes. Crystal structures and photophys. properties of these [9]- and [11]helicene-like mols. were disclosed. [on SciFinder(R)]
