    Synthesis and ion selectivity of all conformational isomers of tetrakis[(ethoxycarbonyl)methoxy]calix[4]arene
    摘要:
    We have found that the conformer distribution in tetra-O-alkylation of 5,11,17,23-tetra-tert-butylcalix[4]-arene-25,26,27,28-tetrol by ethyl bromoacetate is remarkably affected by the metal cation present in the base. In general, the cone conformer predominantly results when the base contains template metal cations whereas the partial-cone and 1,3-alternate conformers result when the base contains nontemplate metal cations. In acetone solvent one can realize the change from the 100% cone selectivity to the 100% partial-cone selectivity. By combining the metal template effect with a protection-deprotection method with a benzyl group, we developed synthetic routes to all of the four conformers. Two-phase solvent extraction established that the cone conformer shows Na+ selectivity whereas the remaining three conformers show K+ selectivity. H-1 NMR studies established that the 1,3-alternate conformer can form both a 1:1 and a 2:1 metal/calixarene complex and the two metal-binding sites display negative allostericity. This paper thus demonstrates that the metal selectivity of ionophoric calix[n]aryl esters can be changed not only by the change in the ring size but also by the conformational change.

  • Easy and Selective Method for the Synthesis of Mono-, Di-, Tri-, Tetra-O-Arylmethyl-P-T-Butylcalix[4]Arenes
    作者:Yuanyuan Xie、Wang Xia
    DOI:10.3184/174751912x13371837407801
    日期:2012.7

    Mono-, di-, tri- and tetra-O-arylmethyl-p-t-butylcalix[4]arenes were synthesised respectively from p-t-butylcalix[4]arene and arylmethyl bromide through an easy and selective one-step reaction. Mono- and di-arylmethyl ethers of p-t-butylcalix[4]arenes were prepared using LiH as a base, while tri- and tetra-arylmethyl derivatives were afforded in the presence of Ba(OH)2 and BaO. These methods are remarkable for excellent selectivity, mild reaction conditions, moderate to good yields and easy purification.

    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

    the p-tert-butylcalix[4]- and -[6]arenes using bis(butyltin)oxide and different alkylating agents is described. The procedure is remarkable for the mild conditions used allowing an efficiently access to monoalkylated calixarene derivatives in moderate to good yields. Monoalkynylcalix[4]arene and monoalkynylcalix[6]arene have been synthetically exploited for the synthesis of bis-calix[n]arenes (n =

    In p-t-butylcalix[4]arene (1H4) and its mono-, di-, tri-, and tetra-O-alkyl derivatives (1HR3, 1H2R2, 1HR3, and 1R4 respectively), 23 different homologs can exist (including 1H4). We found that the OH group in the unmodified phenol unit is permeable through the calix[4]arene ring. Thus, several conformational isomers become equivalent after the oxygen-through-the-annulus rotation of the OH group and

    The first inherently chiral calix[4]crown ethers 2 have been obtained by the base-catalysed reaction of mono-alkylated p-tert-butylcalix[4]arenes 1 with oligoethylene glycol ditosylates. Preliminary 1H NMR studies suggest the ability of these receptors to bind either chiral alkylammonium or Zn2+ guest species within the hydrophilic pocket generated by the O-alkyl residues at the lower rim.
