摘要：
Polymer-supported dicyanolketene acetal (poly-DCKA-1), synthesized by copolymerization of a DCKA bearing a 4-vinylbenzyl group with ethyleneglycol dimethacrylate, was found to be an excellent recyclable catalyst for the three-component Mannich-type reaction of aidehydes, aromatic amines, and TMS enolate of ethyl isobutyrate in water as the sole solvent.
