The chiral ionic liquids have broad applications as inducers for asymmetric reactions. Chiral imidazo1idinones are important sorts of aminocatalysts, which have been attracted much attention in re-search of enantioselective organocatalysis field. From the view of greening and economization, 7 new chiral imidazo1idinone ionic liquids with different anions are synthesized from L-tyrosine, which is a kind of natural chiral materials, through esterfication, amination, cyclization, [3+2] cycloaddition, etc. The structures and properities were characterized by 1H NMR, 13C NMR, ESI-MS, IR, , DSC and TGA methods.

Key words: L-tyrosine, chiral imidazolidinone, click reaction, chiral ionic liquid
