Use of Stille-type cross-coupling as a route to oligopyridylimines
Champouret, Yohan D.M.,Chaggar, Rajinder K.,Dadhiwala, Ishaq,Fawcett, John,Solan, Gregory A.
, p. 79 - 89 (2006)
The new tin reagents, 2-(n-Bu3Sn)-6-{C(R)OCH2CH 2O}-C5H3N, (R=H a, Me b), have been employed in Stille-type cross-coupling reactions with a range of oligopyridylbromides generating, following a facile deprotection step, a series of formyl- and acetyl-functionalised oligopyridines. Condensation reactions with 2,6-diisopropylaniline has allowed access to families of novel sterically bulky multidentate N,N,N,N (tetradentate), N,N,N,N,N (pentadentate), N,N,N,N,N,N (sexidentate) and N,N,N,N,N,N,N (heptadentate) nitrogen donor ligands. This work represents a straightforward and rapid synthetic route for the preparation of oligopyridylimines, which are expected to act as useful components for the self-assembly of polymetallic complexes.
An acyclic oligoheteroaryle that discriminates strongly between diverse G-Quadruplex topologies
Hamon, Florian,Largy, Eric,Guedin-Beaurepaire, Aurore,Rouchon-Dagois, Myriam,Sidibe, Assitan,Monchaud, David,Mergny, Jean-Louis,Riou, Jean-Francois,Nguyen, Chi-Hung,Teulade-Fichou, Marie-Paule

Feeling groovy: A family of nonmacrocyclic G-quadruplex binders with alternate oxazole and pyridine motifs was prepared. The shown heptacyclic derivative exhibits an unprecedented binding preference for certain quadruplex topologies: it recognizes exclusively the human telomeric quadruplex in Na + buffer but not in K+ buffer. This unique quadruplex binding profile is strongly dependent on the size of the ligand and may result from groove interactions. Copyright

Non-symmetrical, potentially redox non-innocent imino NHC pyridine 'pincers': Via a zinc ion template-assisted synthesis
Simler, Thomas,Danopoulos, Andreas A.,Braunstein, Pierre
, p. 5955 - 5964 (2017/07/10)
New non-symmetrical, redox-active imino NHC pyridine pincer ligands, 2-(R1-imidazol-2-ylidene)-6-(R2NCH)-pyridine (R1 = 2,6-diisopropylphenyl (DiPP), R2 = 2,4,6-trimethylphenyl (Mes), 4B; R1 = R2 = DiPP, 4C), have been accessed by a ZnII-promoted modular synthesis involving the quaternization of R1-imidazole by [Zn(κNimineκNpyridine)(2-(R2NCH)-6-bromo-pyridine)Cl2], followed by ZnII removal and deprotonation of imidazolium pro-ligands. Redox active forms of 4B were implicated in the two complexes obtained by its reaction with FeBr2/KC8; metrical data analysis pointed to the occurrence of radical anionic and dianionic redox states of 4B.
