Chemoselective recognition with phosphonate cavitands: the ephedrine over pseudoephedrine case.
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.
متن کاملMetallocyclodextrins: Combining Cavitands with Metal Centres
In the last decades, combining the properties of a transition-metal ion with those of a covalently linked, molecular cavity has attracted a great deal of attention. Numerous studies focused on the design and synthesis of systems exploiting the binding properties of a receptor moiety attached to an active metal site, with the aim of mimicking nature’s metal-containing catalysts: metalloenzymes. ...
متن کاملResorcinarene-based cavitands with chiral amino acid substituents for chiral amine recognition.
Resorcinarene-based deep cavitands alanine methyl resorcinarene acid (AMA), alanine undecyl resorcinarene acid (AUA) and glycine undecyl resorcinarene acid (GUA), which contain chiral amino acids, have been synthesized. The upper rim of the resorcinarene host is elongated with four identical substituents topped with alanine and glycine groups. The structures of the new resorcinarenes were eluci...
متن کاملHalogen-bonded solvates of tetrahaloethynyl cavitands†
Halogen bonding (XB) has been receiving considerably increasing attention as it provides a complementary interaction to hydrogen bonding (HB). XB has been proven to play crucial roles in supramolecular chemistry, nanoscience, biosystems, and functional materials. Its directionality and tunability make XB an important noncovalent interaction, geometrically and thermodynamically, similar to HB; h...
متن کاملCavitands: Molecules with Enhanced Selectivity for Chem/bio Detection
The selective response of supramolecular structures, cavitands, is demonstrated using a sensitive optical transduction scheme, surface plasmon resonance (SPR). The methylene bridged cavitands (MeCav) with shallow cavities do not complex aromatic vapors, the pyrazine bridged cavitands (PzCav) show intermediate selectivity whereas the quinoxaline bridged cavitands (QxCav) with the deepest cavitie...
