  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.
