azide-functionalized support via copper-catalyzed 1,3-dipolarcycloaddition, which efficiently yields a rigid and robust 1,2,3-triazole linkage. The catalytic performance of the corresponding nucleophilic carbenes (NHCs) was examined in intramolecular Stetter reactions (chroman-4-one products) and organocatalytic redox esterifications (α,β-unsaturatedesters). The MeOPEG-immobilized organocatalysts are
