The synthesis of two Fesulphos‐based chiral ligands and their immobilization on a polystyrene support is described. These supported chiral ligands act as very efficient catalysts in 1,3‐dipolar cycloaddition and allylic substitution reactions providing the products with excellent enantioselectivities (91 to >99 % ee ). Filtration of the catalyst from the reaction mixtures allows simple product isolation. The polymer‐supported Cu complex of chiral ligand PS‐ 8 can be recycled without further addition of a copper salt in 1,3‐dipolar cycloaddition reactions.
