These chiral receptors exhibit good chiral recognition ability towards alpha-amino acid ester hydrochlorides (up to K-D/K-L = 4.36, Delta Delta G(O) = - 3.65 kJ mol(-1)) in CHCl3. The molecular recognition abilities and enantioselectivities for guests are also discussed from a thermodynamic point of view. (c) 2007 Elsevier Ltd.
