  Side arm effects on cation binding, extraction, and transport functions of oligopyridine-functionalized aza-crown ethers

  摘要：

  A new series of lariat ethers and double-armed crown ethers was prepared in which oligopyridine-functionalized side arms were attached as secondary donor sites. A novel preparative method of oligopyridine derivatives was successfully applied to the synthesis of these crown ethers. Introduction of an oligopyridine-functionalized side arm into the crown ether system, if of the proper chain length and geometrical arrangement, significantly offered three-dimensional complexation with various metal cations suitable for extraction and transport. Liquid-liquid extraction, C-13-NMR binding, and liquid membrane transport experiments revealed that the present type of double-armed crown ethers exhibited cation-binding abilities superior to corresponding lariat ethers.

  Synthesis of ι-(bromomethyl)bipyridines and related ι-(bromomethyl)pyridinoheteroaromatics: useful functional tools for ligands in host molecules

  摘要：

  Pyridines and 2,2'-bipyridines have been employed as useful ligands in molecular recognition chemistries. Halomethyl-substituted bipyridine or oligopyridine derivatives were required for the assembly of bipyridine or oligopyridine units with a supporting mother functional part in artificial biofunctional molecules. A series of omega-(bromomethyl)bipyridines and related omega-(bromomethyl)pyridinoheteroaromatic compounds (types I-III) were synthesized in this paper. Preparation of oligopyridines and pyridinoheteroaromatic compounds have been carried out by either intermolecular ligand coupling of alkyl heteroaryl sulfoxide with pyridyllithium or intramolecular ligand coupling of pyridyl heteroaryl sulfoxide with methylmagnesium bromide for the type I compounds. The type II and III compounds were synthesized by addition of pyridyllithium to pyridinecarboxaldehyde. The omega-bromo group was introduced by radical bromination reaction of methylpyridyl group using NBS and BPO (dibenzoyl peroxide) or bromination of omega-(hydroxymethyl)pyridine using a combination of CBr4 and Ph3P.

  已知具有双吡啶支架（3,7-二氮杂双环[3.3.1]壬烷）的八齿配体和特别是九齿配体可以有效地与放射性药物化学中感兴趣的一系列金属离子配位，并产生极其稳定和惰性的复合物。九齿双吡啶L 2 （N3 附加三齿联吡啶醋酸盐，N7 附加吡啶甲酸盐）之前已被证明是111 In 3+ 、 177 Lu 3+和225 Ac 3+诊断感兴趣核素的理想螯合剂和治疗，一项针对 SSTR2 特异性奥曲酯的原理验证研究显示了治疗诊断应用的潜力。我们现在已将这些研究扩展到两个方向。首先，我们提出了配体衍生物L 3 ，其中乙酸联吡啶被三联吡啶取代，三联吡啶是金属离子的较软供体，具有更多共价性。 L 3没有实现希望，因为络合作用的效率要低得多。虽然对于 Bi 3+和 Pb 2+来说，配体是一种优异的螯合剂，其性质与L 2相似，但与L 2和225 Ac 3相比，Lu 3+和 La 3+与L 3 的络合作用非常缓慢且效率低下。即使在升高的温度下，
