Our approach of separating the roles of catalytic activity and selectivity in a system, using an established Supramolecular Protecting Group to impart selectivity to catalytic reactions, can produce chiral products (over 90% ee) from racemic feedstocks, employing otherwise-unselective (lowcost and recyclable) solid catalysts. We have also demonstrated that these low-cost catalysts can be recycled, that modular 'catalyst swapping' does not hinder selectivity, and that all this can be used in an unprecedented synthesis of the chiral drug (R)cinacalcet from a racemic starting material. We note that this SPG approach is distinct to Supramolecular Catalysis, as molecular recognition is employed to prevent reaction (just as covalent protecting groups are distinct from covalent chiral auxiliaries).
