title: A molecular receptor for zwitterionic phenylalanine.
abstract: The combination of a 1,3-ketoenol system and two pyridine molecules attached as sulfonamide and carboxamide to a benzofuran skeleton allows the preparation of a novel chiral receptor for zwitterionic phenylalanine association. Interestingly, no crown-ether, urea or guanidinium are necessary to carry out the extraction of amino acids from the aqueous solution, which constitutes a breakthrough in comparison with other receptors for zwitterionic amino acid extraction.
