  IMPROVEMENT OF HELIX-FORMING ABILITY OF MANNOSIDE-LINKED ETHYNYLPYRIDINE OLIGOMERS CONSTRUCTED BY CONVERGENT SYNTHESIS

  摘要：

  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.

  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.
