✦ Synopsis
The polymer-supported organocatalyst was prepared by ion exchange reaction of MacMillan iminium catalyst with polymer-supported sulfonic acids. Resulting polymeric organocatalyst was effective for Diels-Alder reaction of 1,3-cyclopentadiene and trans-cinnamaldehyde in CH 3 OH/H 2 O, affording good enantioselectivity and reusability.
