摘要

Total control of axial and helical chirality 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 enantiopure sulfinyl benzoquinone.
