  Development of convergent synthetic method for saccharide-linked ethynylpyridine foldamers by Huisgen reaction

  摘要：

  Based on 'click chemistry', the new convergent synthesis to a variety of saccharide-linked 2,6-pyridylene ethynylene 'ethynylpyridine' foldamers was developed. Ethynylpyridine 6-, 9-, and 12-meric blocks were linked with 1,7-octadiyne linker block by Sonogashira reaction, and joined with azido group-introduced glucoside, galactoside, and mannoside templates by Huisgen reaction. The resulting saccharide-linked ethynylpyridine foldamers exhibited typical circular dichroism to indicate the formation of a helical structure by intramolecular hydrogen bonds.

• IMPROVEMENT OF HELIX-FORMING ABILITY OF MANNOSIDE-LINKED ETHYNYLPYRIDINE OLIGOMERS CONSTRUCTED BY CONVERGENT SYNTHESIS
  作者：Masahiko Inouye、Hajime Abe、Hiroki Makida

  DOI：10.3987/com-12-s(n)97

  日期：——

  The improvement of helix-forming ability of a-D-mannoside-linked 2,6-pyridylene ethynylene "ethynylpyridine" oligomers was made by modification of the linker between the ethynylpyridine and mannoside moieties in the oligomers. The linker involves a triazole ring because the preparation utilizes Huisgen reaction, and the proper distance between the triazole ring and the ethynylpyridine moiety was found to be important to show strong Cotton effects.
