A novel copper-catalyzed atroposelective diyne cyclization enables the efficientsynthesis of a range of axially chiral arylpyrrole biaryls in good to excellent yields with generally excellent enantioselectivities via oxidation and X−H insertion of vinyl cations. This method gives the first synthesis of mono-substituted 3-arylpyrrole atropisomers and the first atroposelective diyne cyclization.
