Abstract
This review highlights the advances in molecular recognition based on the linear molecular receptors in the past decade. Three kinds of linear receptors that bind discrete neutral, cationic and anionic organic molecules, metal ions, and halide anions are described. The first are foldamer receptors that are induced by intramolecular non-covalent forces to spontaneously fold into compact conformations. The second are linear molecules that themselves are structurally flexible but turn into folded conformations upon binding. The third are functionalized foldamers that consist of hydrogen bonding-driven preorganized arylamide-based linkers and attached binding sites fullerene units.
Keywords: Molecular recognition, supramolecular chemistry, foldamer, linear receptor, non-covalent interaction, m-Phenyleneethynylene (mPE) Foldamers, DMAP, groove binding, ICD signals, α- and β-D-glucoses, Ethynylindolyl Oligomer Foldamers, Oligopyridine-dicarboxamide strands, Pyridine-Naphthyridine Oligomers, Triazole-Benzene Oligomers, OLIGOCHOLATE

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
