Bottom-up chem. synthesis to construct intricate mols. is a profound challenge. An effective approach is to use organic ligands and metal ions, but the formation of a single product among other possible candidates proved difficult for dissym. structures. The authors now report the synthesis of single isomeric complexes with dissym. structures using the mismatch in the coordination valences of macrocyclic homooligomers and metal ions. Amide-cyclodextrin derivatives possessing multiple 2,2′-bipyridyl (bpy) groups forms mononuclear complexes whose specific three bpy groups are linked in the fac-Λ configuration. The intermol. coordination of the β-cyclodextrin metal complex produces a dissym. cyclodextrin trimer as a single isomer, whose initially equivalent 21 (7×3) bipyridylamide-pyranose units are placed in different environments. Also, the authors realize chiral recognition of amino acid anions using the distinctive amide groups arranged on the unsym. fixed scaffold. The results came from multiple reactions, including the reaction of 2-Bromo-5-methylpyridine(cas: 3510-66-5Application of 3510-66-5)
2-Bromo-5-methylpyridine(cas: 3510-66-5) belongs to pyridine. Pyridines are often used as catalysts or reagents; particular notice has been paid recently to how pyridine coordinates to metal centers enabling a wide range of valuable reactions. Application of 3510-66-5
