Features and Benefits

This support amine has been developed to serve as a Knoevenagel catalyst. Because it is polymer-bound, it eliminates piperidine-derived by-products and reduces transesterification while using alcohol as a solvent. Recently, this resin was shown to be recyclable in the synthesis of benzopyrones using "resin capture" methodology.
