Tetracarbonylmolybdenum complexes of 2-(phenylazo) pyridine ligands. Correlations of molybdenum-95 chemical shifts with electronic, infrared, and electrochemical properties
Ackermann, Martin N.,Fairbrother, William G.,Amin, Neelim S.,Deodene, Charles J.,Lamborg, Carl M.,Martin, Paul T.
, p. 145 - 151 (1996)
The complexes cis-Mo(CO)4(X-2-(phenylazo)pyridine) (X = 4-CH3O, 4-CH3, H, 4-Cl, 5-Br, 5-CF3, 6-CH3) and cis-Mo(CO)4(2-(2-CH3-phenylazo)pyridine) have been synthesized and characterized by cyclic voltammetry, by visible and infrared spectroscopy, and by 1H, 13C, and 95Mo NMR spectroscopy. The 95Mo chemical shift correlates with the lowest energy electronic transition, with the sum of the carbonyl stretching frequencies, with the first oxidation potential, and with Hammett σ parameters for the pyridyl substituents. The failure of the complexes cis-Mo(CO)4(6-CH3-2-(phenylazo)pyridine) and cis-Mo(CO)4(2-(2-CH3-phenylazo)pyridine) to fit some of the correlations is attributed to steric or electronic effects. The effect of a substituent on the pyridyl ring of 2-(phenylazo)pyridine appears to be entirely an inductive one operating through the σ bonding. It is suggested that the 2-(phenylazo)pyridines might be appropriately viewed as ligands whose strong π-acceptor ability resides with the azo group, while the pyridyl group acts primarily as a pyridine whose basicity has been decreased by the strong electron-withdrawing 2-phenylazo substituent.
A convenient synthetic route to substituted pyrrolo[2,3-b]pyridines via a novel ethylene-bridged compound

, p. 6606 - 6609 (2015)
A convenient synthetic route to 4-substituted pyrrolo[2,3-b]pyridines is presented. The novel ethylene bridged compound 1,2-bis(4-azidopyrrolo[2,3-b]pyridinyl)ethene was prepared and further derivatized. The novel synthesis was applied in the preparation of 3-cyano-4-hydroxypyrrolo[2,3-b]pyridine.

A new three-component reductive arylation of amides with stable reactants (iPrOH and arylboronate esters), making use of a 2-pyridinyl (Py) directing group, is described. The N-Py-amide substrates are readily prepared from carboxylic acids and PyNH2, and the resulting N-Py-1-arylalkanamine reaction products are easily transformed into the corresponding chlorides by substitution of the HN-Py group with HCl. The 1-aryl-1-chloroalkane products allow substitution and cross-coupling reactions. Therefore, a general protocol for the transformation of carboxylic acids into a variety of functionalities is obtained. The Py-NH2 by-product can be recycled.
BCR-ABL TYROSINE-KINASE LIGANDS CAPABLE OF DIMERIZING IN AN AQUEOUS SOLUTION, AND METHODS OF USING SAME
-
Paragraph 00592; 00603; 00604, (2015/07/23)
Described herein are monomers capable of forming a biologically useful multimer when in contact with one, two, three or more other monomers in an aqueous media. In one aspect, such monomers may be capable of binding to another monomer in an aqueous media (e.g. invivo) to form a multimer (e.g. a dimer). Contemplated monomers may include a ligand moiety, a linker element, and a connector element that joins the ligand moiety and the linker element. In an aqueous media, such contemplated monomers may join together via each linker element and may thus be capable of modulating one or more biomolecules substantially simultaneously, e.g., modulate two or more binding sites on a Bcr-Abl tyrosine kinase.

A range of different N- and S-containing heterocyclic bromides can be efficiently coupled with gaseous ammonia in the presence of copper(II) acetylacetonate [Cu(acac)2] as catalyst and in the absence of additional ligands. Unstable aminothiophenes and aminobenzothiophenes can be further reacted in situ to afford functionalized derivatives. Copyright
