title: Chemoselective recognition with phosphonate cavitands: the ephedrine over pseudoephedrine case.
abstract: Complete discrimination of ephedrine and pseudoephedrine, both in solution and in the solid state, was achieved with a phosphonate cavitand receptor. The molecular origin of the epimer discrimination was revealed by the crystal structure of the respective complexes.
