A convergent synthetic route for various saccharide−linked ethynylpyridine oligomers

Abstract

To prepare various saccharide−linked ethynylpyridine oligomers convergently, we developed synthetic routes in which a saccharide template was coupled with ethynylpyridine oligomers by Huisgen reaction in the final step. The higher−order structures of the oligomers were studied by UV-vis and CD spectroscopy in dichloromethane. The induced CD spectra revealed that the chirality of saccharide templates was transferred to the chirality of the helical structures of the oligomers.
