Research advance of synthesis of nitrogenous chiral ionic liquids and its application

The research advance of synthesis of various nitrogenous chiral ionic liquids such as imidazolium,ammonium,pyridinium,etc.and its application in asymmetric catalytic reactions was summarized.The chiral ionic liquids were prepared either from the chiral pool such as aminoacids,aminoalcohols,or alkaloids,or by asymmetric synthesis.The future study focus will be put on the construction of chiral center,preparation methods of immobilised chiral ionic liquids,and research of relations between structure and character of nitrogenous chiral ionic liquids.
