  N-Linked Peptidocalix[4]arene Bisureas as Enantioselective Receptors for Amino Acid Derivatives

  摘要：

  Bisurea calix[4]arenes 1 and 2 possessing L-amino acid moieties at the lower rim were synthesized by reaction of the methyl esters of glycine, L-alanine, or L-isoleucine with the appropriate isocyanate (12 or 13), obtained with a safe and efficient Curtius rearrangement from the corresponding carboxylic acid derivatives. The conformational properties of the ligands 1 and 2 were investigated by means of a combined NMR and molecular modeling study which evidences that they are deeply influenced by strong intramolecular H-bonds between the urea NH groups and the vicinal phenolic oxygen atoms or the opposite urea CO group. Complexation studies performed by ESI-MS and NMR spectroscopy in acetone solution show that the binding ability of these bisurea hosts decreases by increasing the side chain size of the amino acid. Host 2b has a remarkable binding ability for the N-acetyl-D-phenylalaninate anion with an interesting enantioselectivity (K-ass(D)/K-ass(L) = 4.14), which is explained on the basis of a three-point interaction mode of binding.

  Inherently chiral calix[4]arenes (9,10) with carboxamide bridges spanning the proximal positions on the lower rim and 18 achiral counterparts have been synthesized by double intramolecular cyclization of 7b,8b 1,3-and 17 1,2-bis-chloroalkylamides. The conformational analysis of the 1.3- and 1,2-disubstituted calixarene intermediates 5–8 and 15–17 proved an equilibrium of two distorted cone conformations

  In this paper, di-tripodal amine calix[4]arene, L1, was successfully synthesized and used as an ion carrier in poly(vinyl chloride) (PVC) membrane electrodes. Compound L1 was employed to demonstrate a new concept in anion sensing by preparing an allosteric PVC membrane that can respond selectively to a certain anion in the presence of a metal effector. Membranes containing compounds L1 and potassium tetrakis(p-chlorophenyl)borate (KTpClPB) as an ionic additive showed Donnan exclusion failure upon measuring the potential (EMF) responses of Cu2+ and responded to the co-anion by giving negative EMF changes, while membranes containing compound L2, an anthracene-based mono-tripodal amine ligand, gave positive potentials to most metal ions. Upon preconditioning of the membranes containing L1 and 75 mol% KTpClPB in CuCl2, the membranes showed the highest selectivity towards thiocyanate with a near Nernstian slope of −59.6 mV decade−1, a 10−5 to 10−2 M linear range, and a detection limit of 4.4 × 10−6 M. The best allosteric membrane can be used in the pH range 3–7 with good reversibility, and also applied to indirectly determine the concentration of Fe3+ in aqueous solution.
