Non-interpenetrating starpolymercatalysts designed to mimic the site isolation characteristics of enzymes enable the one-pot combination of multiple otherwise incompatible catalysts for asymmetric cascadereactions that involve iminium, enamine, and H-bonding catalysis. Control experiments replacing starpolymercatalysts with the corresponding small molecule or linear polymer analogues lead to little
