Poly(amide-triazole)s obtained by regioselective, microwave-assisted click polymerization of bio-based monomers

The Cu(I)-catalyzed, microwave-assisted click polymerization of bio-based α-azide-ω-alkyne monomers afforded, with high regioselectivity, stereoregular poly(amide-triazole)s. The monomers were prepared starting from d-glucono-1,5-lactone as a renewable resource. The synthetic route involves the sele...

The synthetic route involves the selective protection of this sugar lactone with formaldehyde to give a gluconic acid derivative, which was subjected to amidation of the carboxylic acid function with alkynylamines (2-propynyl, 3-butynyl, and 4-pentynylamines) and substitution of the primary hydroxyl group by azide.
