Abstract
Merrifield resin supported ionic liquids/l-proline as efficient and recyclable catalyst systems for asymmetric aldol reaction have been developed. l-Proline with Merrifield resin supported ionic liquids can catalyze asymmetric aldol reaction smoothly and generate the corresponding products in good to excellent yields and ee values. In addition, the supported catalyst systems can be recycled simply by filtration and reused for five times without significant decrease in activity.
Key words
Merrifield resin - organocatalyst - aldol reaction - l-proline - ionic liquids - supported catalysts
