A general, chemical/chiroptical approach based on the CD exciton chirality method has been developed to determine the absoluteconfiguration of α-hydroxy acids. This approach consists of amidation of the carboxyl group with ethanolamine followed by derivatization with the hydrophobic 10,15,20-triphenylporphyrinyl-5-benzoyl chromophore to form π,π-bisporphyrin derivatives which undergo intramolecular
