Combination of a binaphthyl unit with chromenone benzoxazole fragments provided a chiral receptor that is enantioselective for glutamic acid and its derivatives. The receptor racemic mixture was resolved by TLCs impregnated with (R,R)-thiodilactic acid. High association constants were measured for dansylglutamic acid, using a fluorescent method. This receptor can be used for the resolution of the tosylglutamic acid racemic mixture.
