Anion recognition properties of pyridine-2,6-dicarboxamide and isophthalamide derivatives containing l-tryptophan moieties

摘要

l-Tryptophan containing anion receptors 1 and 2 have shown interesting features. Receptor 1 behaves as a hetero-ditopic dicompartimental receptor for fluoride and chloride with a certain selectivity for fluoride as supported by 1H NMR titrations and molecular modeling, while receptor 2 forms only 1:1 complexes. Moreover, receptor 1 reveals a certain affinity towards the l enantiomers of amino acids alanine and serine.View full textDownload full textKeywordsanion recognition, ditopic receptors, enantiomeric discriminationRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10610278.2011.628391
