title: Ir-catalyzed almost perfect enantioselective synthesis of helical polyaryls based on an axially-chiral sequence.
abstract: Ir-catalyzed enantioselective [2 + 2 + 2] cycloaddition of tetraynes or an octayne with monoalkynes proceeded to give helically-chiral quinquearyl and noviaryl compounds, which respectively have four and eight consecutive axial chiralities, in an almost enantiomerically pure form.
