A Sustainable Route towards Imidazolium Building Blocks Based on Biomass Molecules

Make it green: An efficient one-pot procedure for the synthesis of homosubstituted imidazolium compounds on the basis of renewable precursors is reported. By starting from amino acids and pyruvaldehyde, a library of bifunctional imidazolium scaffolds for the construction of polymers and ionic liquids was prepared (see scheme).
