A novel family of chiral ammonium-based ionic liquids containing a chiral moiety and a free hydroxyl function has been designed and synthesized from isosorbide. The synthesis of these ionic liquids is easy and practical owing to the commercially available starting materials. These new chiral ionic liquids can be used as chiral reaction media as well as catalysts in asymmetric synthesis, which are currently being investigated in our laboratory.
