Abstract
Direct asymmetric α-amination of unmodified aldehydes with azodicarboxylates in ionic liquids in the presence of imidazolium ion-tagged l-proline organocatalyst 1 gives excellent enantioselectivities (up to 98% ee) and high chemical yields. The system can be easily recycled and reused for at least four times without significant loss of yields and enantioselectivity.
