Total control of axial and helicalchirality elements of a (2-biphenyl)-substituted tetrahydro[5]helicene quinone and the configurationally stable dihydro[4]helicene analogue was achieved in a dynamic kinetic resolution process of an axially chiral racemic diene promoted by an enantiopuresulfinyl benzoquinone.
