Five chiral calix[4]proline derivatives were designed and synthesized from aminocalix[4]arenes, and their structures were characterized by 1H NMR, 13C NMR, IR, ESI-MS and elemental analysis. The chiral recognition ability for enantiomers of mandelic acid was investigated by NMR techniques, and the results showed that 5,11-diprolinamides substituted calix[4]arene 2b could well and selectively recognize the two enantiomers of mandelic acid (KL/KD≈94). A possible recognition mechanism was proposed, which was constructed by cooperative multi-supramolecular interactions including intermolecular acid-base, hydrogen bond and π···π stacking interactions.

Key words: calix[4]arene, L-proline, mandelic acid, chiral recognition, NMR
