Chiral, tripodal anion hostsderivedfrom either S-phenylalanine or S-leucine bind D-lactate enantioselectively. The nature of the host–guest interaction has been probed by solution NMR methods and by DFT calculations. The calculations suggest that the D-lactate may form an additional hydrogen bond in the host–guest complex while the L-lactate complex contains an intramolecular hydrogen bond. Anion
