We have introduced a new enantioselective receptor 1 by incorporation of chiral building blocks to the previously reported carboxylate selective receptor 2. Binding studies carried out using $^1H$ NMR revealed that the receptor 1 showed moderate enantioselectivity with a general preference for D-amino acids and a highest enantioselectivity for leucine among the amino acids we investigated.
