Abstract :
Good chiral recognition of hydroxycarboxylates such as lactic or mandelic acids has been achieved with a macrocyclic receptor, readily available from a known bis-chromenylurea and a spirobifluorene linker. Resolution of the receptor racemic mixture was carried out taking advantage of its complexing properties with (R)-mandelic acid tetramethylammonium salt on a TLC plate.
