structurally new roomtemperaturechiralionicliquids based on an imidazolium group and derived from natural aminoacids have been synthesized and studied as chiral shift agents for the chiral discrimination of enantiomeric carboxylate salts. This family of imidazolium salts can be prepared by a simple synthetic approach and most of the components are liquid at roomtemperature. The solid to liquid transformation

Chiralionicliquids derived from natural amino acids are shown to be green and efficient media for direct asymmetric aldolreactions at room temperature catalyzed by (S)-proline. The corresponding aldol products were obtained with moderate to good enantioselectivities. A transfer of chirality from the chiralreaction media has been observed as well as the
