Abstract
2-Azidomethyl-5-ethynylfuran, a new ambivalent compound with both azide and alkyne
moieties that can be used as a self-clickable monomer, is synthesized starting directly
from renewable biomass. The reactivity of the azide group linked to furfural is tested
via the efficient preparation of a broad range of furfural-containing triazoles in
good to excellent yields using a ‘green’ copper(I)-catalyzed azide–alkyne cycloaddition
procedure. Access to new bio-based chemicals and oligomeric materials via a click-chemistry
approach is also demonstrated using this bio-derived building block.
Key words 5-(hydroxymethyl)furfural - click chemistry - biomass conversion - triazoles - oligomers
