A novel imidazolium ion‐tagged L ‐proline catalyst has been developed. The asymmetric α‐aminoxylation of aldehydes and ketones with excellent enantioselectivities, up to 99% ee , and high yields in ionic liquids has been achieved. The system can be easily recycled and reused for at least six times without significant loss of yields and enantioselectivity.
