The design and synthesis of recyclable imidazolidinone catalysts using GAP chemistry/technique was described. Their applications in asymmetric Diels-Alder and Friedel-Crafts reactions with α,β-unsaturated aldehydes resulted in excellent yields and higher enantioselectivities than previous processes. As recyclable small molecular catalysts, phosphonylated imidazolidinones can be recovered and reused for up to three runs without costing significant decrease in catalytic activity.

A heterogeneous chiral imidazolodinone catalyst was synthesized by immobilization on a sulfated chitin through non-covalent ionic interactions. The chitin-based organocatalyst promoted the asymmetric Diels-Alder reaction with high enantioselectivity under heterogeneous conditions and was successfully reused multiple times without apparent loss of catalytic activity and enantioselectivity.

The synthesis of chiral imidazolidinones on mesoporous silica nanoparticles, exploiting two different anchoring sites and two different linkers, is reported. Catalysts 1-4 were prepared starting from l-phenylalanine or l-tyrosine methyl esters and support
