Bimetallics in a Nutshell: Complexes Supported by Chelating Naphthyridine-Based Ligands

Bimetallic motifs are a structural feature common to some of the most effective and synthetically useful catalysts known, including in the active sites of many metalloenzymes and on the surfaces of industrially relevant heterogeneous materials. However, the complexity of these systems often hampers detailed studies of their fundamental properties. To glean valuable mechanistic insight into how these catalysts function, this research group has prepared a family of dinucleating 1,8-naphthyridine ligands that bind two first-row transition metals in close proximity, originally designed to help mimic the proposed active site of metal oxide surfaces. Of the various bimetallic combinations examined, dicopper(I) is particularly versatile, as neutral bridging ligands adopt a variety of different binding modes depending on the configuration of frontier orbitals available to interact with the Cu centers. Organodicopper complexes are readily accessible, either through the traditional route of salt metathesis or via the activation of tetraarylborate anions through aryl group abstraction by a dicopper(I) unit. The resulting bridging aryl complexes engage in C-H bond activations, notably with terminal alkynes to afford bridging alkynyl species. The mu-hydrocarbyl complexes are surprisingly tolerant of water and elevated temperatures. This stability was leveraged to isolate a species that typically represents a fleeting intermediate in Cu-catalyzed azide-alkyne coupling (CuAAC); reaction of a bridging alkynyl complex with an organic azide afforded the first example of a well-defined, symmetrically bridged dicopper triazolide. This complex was shown to be an intermediate during CuAAC, providing support for a proposed bimetallic mechanism. These platforms are not limited to formally low oxidation states; chemical oxidation of the hydrocarbyl complexes cleanly results in formation of mixed valence (CuCuII)-Cu-I complexes with varying degrees of distortion in both the bridging moiety and the dicopper core. Higher oxidation states, e.g., dicopper(II), are easily accessed via oxidation of a dicopper(I) compound with air to give a Cu-2(II)(mu-OH)(2) complex. Reduction of this compound with silanes resulted in the unexpected formation of pentametallic copper(I) dihydride clusters or trimetallic monohydride complexes, depending on the nature of the silane. Finally, development of an unsymmetrical naphthyridine ligand with mixed donor side-arms enables selective synthesis of an isostructural series of six heterobimetallic complexes, demonstrating the power of ligand design in the preparation of heterometallic assemblies.

CONDENSED ISOQUINOLINES. 37. HETEROCYCLIZATION USING 3-(ARYLAMINO)- AND 3-(HETARYLAMINO)ISOQUINOLIN-1(2H)-ONES

The reaction of 3-NHR-isoquinolin-1(2H)-ones (R = Ar) with aromatic aldehydes in the presence of Me3SiCl or in acetic acid leads to the formation of derivatives of dibenzo[b,f][1,8]naphthyridin-5(6H)-one and benzo[f]isoquino[3,4-b][1,8]naphthyridine-5,9(6H, 7H)-dione. The reaction for R = Het in the presence of Me3SiCl gives derivatives of 5H-pyrido[1′,2′:1,2]pyrimido[4,5-c]isoquinolin-5-one, benzo[f]isoquinoline[3,4-b][1,8]naphthyridine-5,9[6H,7H]-dione, and derivatives of new heterocyclic systems, 5H-pyrazino[1′,2′:1,2]pyrimido[4,5-c]isoquinolin-5-one, 5H-[1,3]thiazolo[3′,2′:1,2]pyrimido-[4,5-disoquinolin-5-one, 5-H-benzo[f]pyrazolo[3,4-b][1,8]naphthyridin-5-one, and isoquino[3,4-b]1,5]naphthyridin-5(6H)-one.

Synthesis and comparative solvatochromic studies of simple and donor acceptor benzimidazole incorporated naphthyridine systems

Benzimidazo[1,2-a]benzo[g]-1,8-naphthyridine (NB-1) and its donor-acceptor analog, 11-morpholino-benzimidazo[1,2-a]benzo(g)-1,8-naphthyridine-6-carbonitrile, (NB-2) have been synthesized and investigated for their optical and solvatochromic properties. Absorption and emission maxima of the push-pull chromophore, NB-2 were red shifted in comparison to NB-1 lacking in donor-acceptor motif. Both systems are highly fluorescent (phi = 0.74-0.84) and exhibit positive solvatochromism. Using solvatochromic shift method, we estimated 2 fold higher dipole moment in the excited state for NB-2 over NB-1. High degree of electronic charge redistribution in NB-2 seems to be responsible for its optical spectral red shifts and higher dipole moments compared to NB-1.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 126-30-7 is helpful to your research. Computed Properties of C5H12O2.

Targeting multiple G-quadruplex-forming DNA sequences: Design, biophysical and biological evaluations of indolo-naphthyridine scaffold derivatives

It is well recognized that the non-canonical DNA structures known as G-quadruplexes (G4s) have a potential anticancer significance and several compounds have been discovered and evaluated as promising G4 binders with anticancer activity. Here, starting from a promising hit with an indolo-naphthyridine scaffold, a small series of five indolo-naphthyridine based derivatives have been designed and evaluated as G4-targeting compounds. FRET biophysical studies were performed on multiple DNA G4 structures, leading to the identification of a multi-target G4 stabilizer with a slight preference for the c-KIT1 and a good G4 over duplex selectivity. The good affinity of this compound against c-KIT1 G4 was also confirmed by SPR and MST experiments, while biological assays revealed its cytotoxic activity on tumour cells. Finally, Molecular Dynamics simulations helped to elucidate the stabilization effect of the selected compound against the c-KIT1 G4. (C) 2019 Elsevier Masson SAS. All rights reserved.
