A novel poly(N-isopropyl-acrylamine-co-l-proline) catalyst for aldol reaction: synthesis, catalytic performance and recyclability

Abstract

A novel homogeneous copolymer catalyst was synthesized via single step radical copolymerization and developed for the aldol reaction. It was demonstrated that the catalyst possessed excellent activity and stereoselectivity. The secondary structure of the copolymer catalyst was evaluated by circular dichroism. Furthermore, the catalyst was readily recovered without loss of conversion and stereoselectivity even after ten cycles.
