From optically pure [6]helicene-like alcohol four phosphites were prepared, which were applied to the asymmetric hydroformylation and the asymmetric allylic amination exhibiting high enantioselectivity (up to 94% ee). This study represents the first use of helicene-like ligands in asymmetric reactions.
