the lead: The title method for the identification of ligands is particularly useful for bindingsites where little or no structural information is available. In a fragment‐based approach, a suitable pair of first‐ and second‐siteligands is identified by NMR experiments. By applying a receptor‐mediated in situcombinatorialapproach, the two ligands are then linked to generate a new high‐affinity lead
