A Chiral Pyrrolic Tripodal Receptor Enantioselectively Recognizes beta-Mannose and beta-Mannosides

Chiral is better! Superior recognition properties are shown by a pyrrolic tripodal receptor featuring a chiral diamine in its architecture. Highly enantioselective recognition of the beta-mannosyl residue is achieved by one of the two enantiomers of the receptor, with remarkable affinity in a polar medium and distinct alpha/beta selectivity.
