Ionic Liquids in Asymmetric Synthesis: An Overall View from Reaction Media to Supported Ionic Liquid Catalysis

摘要

Ionic liquids, as a special class of organic compounds, have attracted ever-growing interest in recent years. They have been employed in many organic transformations as a green alternative to volatile organic solvents and as a catalyst to modify catalytic activity and recyclability. Recent developments have demonstrated that ionic liquids might also have many benefits in asymmetric reactions. In this review, we survey the use of ionic liquids in asymmetric transformations, including the use of ionic liquids as reaction media in asymmetric reactions, ionic-liquid-tagged chiral catalysts for use in asymmetric synthesis, and supported ionic liquid catalysts in asymmetric transformations.
