Item Enantioenrichment of racemic BINOL by way of excited state proton transfer(Royal Society of Chemistry, 2019) Ayad, Suliman; Posey, Victoria; Das, Anjan; Montgomery, Jason M.; Hanson, KennethHere we report a method for enantioenriching BINOL using a chiral auxiliary and an excited state proton transfer (ESPT) event. Regardless of the starting enantiomeric excess (ee), after irradiation the solution reaches a photostationary state whose ee is dependent solely on the identity of the chiral auxiliary group. The enantio-enriched BINOL is easily recovered by cleaving the auxiliary group in mild conditions.
