    Stability and Lifetime of Quadruply Hydrogen Bonded 2-Ureido-4[1H]-pyrimidinone Dimers
    摘要:
    2-Ureido-4[1H]-pyrimidinones are known to dimerize via a strong quadruple hydrogen bond array. A. detailed study of the dimerization constant and lifetime of the dimer is presented here. Excimer fluorescence of pyrene-labeled 2-ureido-4[1H]-pyrimidinone Ib was used to determine a dimerization constant K-dim, of 6 x 10(7) M-1 in CHCl3, 1 x 10(7) M-1 in chloroformsaturated with water, and 6 x 10(8) M-1 in toluene (all at 298 K). Under these conditions, the preexchange lifetime of the similar dimers of both 1d and 1e is 170 ms in CDCl3, 80 ms in wet CDCl3, and 1.7 s in toluene-dp, as determined by dynamic NMR spectroscopy Association rate constants were calculated from the Kdim values and the preexchange lifetimes. The resulting values are significantly lower than the diffusion-controlled association rate constants calculated using the Stokes-Einstein and the Debeije equations. This difference is ascribed to a tautomeric equilibrium of the monomer between the dimerizing 4[1K]-pyrimidinone and nondimerizing 6[1H]-pyrimidinone tautomers, which is unfavorable for dimerization.

    Electronic substituent effects on hydrogen-bonding motifs modulate supramolecular polymerisation
    摘要:
    氢键组装的超分子聚合物作为刺激响应材料受到了极大的关注,这种材料可以利用易于纯化的小型有机分子来获得。决定材料在稀溶液中特性的一个关键特征是超分子合成物之间的相互作用强度。在这项工作中,我们说明了与氢键基团共轭的电子取代基对超分子聚合度会产生微妙但重要的影响。利用脲基嘧啶(含有与自互补氢键基团直接电子通信的电子捐赠苯酚酯和苯甲酸酯连接),扩散有序光谱(DOSY)显示了超分子聚合程度的可预测差异。

  • Intermolecular <sup>2h</sup><i>J</i><sub>NN</sub> Coupling in Multiply Hydrogen-Bonded Ureidopyrimidinone Dimers in Solution

    15N-Labeled ureido-4[1H]-pyrimidinones 4a and 5a were synthesized in order to investigate hydrogen bonding in the strongly hydrogen-bonded dimers in solution with intermolecular (2h)J(NN) coupling. Both direct-detection (15)N NMR and one-dimensional (15)N INADEQUATE (for smaller scalar coupling constants) were employed to determine the coupling constants. For dimers of 4 in CDCl(3), a temperature-dependent

    Substitution of hydrogen bond directed supramolecular assemblies with ethylene glycol chains leads to a reduction in the association constant in apolar solvents, where the reduction of the association constant is dependent on the length of the aliphatic spacer connecting the hydrogen bonds and the ethylene glycol chain.

    Blocked isocytosine isocyanates are conveniently obtained by the reaction of 1,1′-carbonyldiimidazole (CDI) with isocytosines. The resulting precursors for quadruple hydrogen-bonded structures can be isolated and stored for further use. Reaction with either aliphatic or aromatic amines gives the corresponding mono-, bi-, or trifunctional ureidopyrimidinone derivatives in good to excellent isolated
