Abstract
Introduction: We synthesized proline functionalized ionic liquid and further characterized it with analytical techniques.
Method: After getting proper structural information on the above ionic liquid, we utilized them as a catalyst for the asymmetric Mannich-Type Reaction.
Result: We synthesized 6 different types of β-amino α-cyano sulfones derivatives as Mannich adduct using various combinations of different imines and aryl sulphonyl as pre-nucleophiles.
Conclusion: We obtained the corresponding chiral Mannich adduct followed by simple ether washing in excellent yield and stereoselectivity. We recycled the catalyst up to 6 runs without losing the catalytic activity.
