The processing and transfer of stereochemical information is based on communication between two chiral units or between a chiral and a prochiral unit. Stereoselective processes often rely on chirality transfer from a chiral ligand to a catalytically active (metal) center.[1, 2] In supramolecular chemistry,[3] the interaction of a substrate with a receptor (which might be a catalyst) follows the lock and key principle,[4] and an “induced fit” between the ...
