Combinatorial Synthesis of Fused Tetracyclic Heterocycles Containing [1,6]Naphthyridine Derivatives under Catalyst Free Conditions

A three-component reaction between an aromatic aldehyde, an amine, and tert-butyl 2,4-dioxopiperidine-1-carboxylate in EtOH at refluxing temperature gave fused tetracyclic heterocycles in high yields.

Synthesis of furo[2,3-c]-2,7-naphthyridine derivatives via domino heterocyclization reaction

2-Amino-4-cyanomethyl-6-dialkylamino-3,5-pyridinedicarbonitriles were found to react with substituted oxiranes yielding 5,6-diamino-8-dialkylamino-1,2-dihydrofuro [2,3-c]-2,7-naphthyridine-9-carbonitriles. The oxirane ring was shown to be opened selectively from the unsubstituted side and further cyclization occurred with participation of 3-CN, but not 5-CN of the starting pyridines. The furonaphthyridines obtained were converted into 2-dialkylamino-5-methyl-9,10-dihydro-4H-furo[2,3-c]pyrimido[4,5,6-ij]-2,7-naphthyridine-l-carbonitriles and 2-dialkylamino-5,6,9,10-tetrahydro-4H-spiroffuro[2,3-c]pyrimido[4,5,6-ij]-2,7-naphthyridine-5,1′-cyclohexane}1-carbonitriles by treatment with acetic anhydride and cyclohexanone, respectively. The structure of prepared compounds was confirmed unambiguously by X-ray crystallographic study. (c) 2005 Elsevier Ltd. All rights reserved.

Reusable Fe3O4/ZnO/MWCNTs Magnetic Nanocomposites Promoted Synthesis of New Naphthyridines

The Fe3O4/ZnO/MWCNTs magnetic nanocomposites as a high performance organomettalic catalyst was employed for the preparation of naphthyridine derivatives in high yields via five component reaction of isoquinoline, dialkyl acetylenedicarboxylates or propiolates, alpha-haloketones, triphenyphophine and ammonium acetate in aqueous media at ambient temperature. The Fe3O4/ZnO/MWCNTs MNCs were synthesized using ionic liquid [OMIM]Br as a stabilizer and soft template. As well Fe3O4/ZnO/MWCNTs MNCs show a good improvement in the yield of the product and showed significant reusable ability. Due to having isoquinoline core, we investigate antioxidant property of some synthesized compounds by diphenyl-picrylhydrazine (DPPH) radical trapping and power of ferric reduction experiment. Furthermore, the disk diffusion test on Gram positive and negative bacteria are utilized for investigation of antimicrobial activity of some naphthyridines. The achieved outcomes of this experiment demonstrate that these synthesized compounds could prevent from growth of bacteria. Short time of reaction, high yields of product, easy separation of catalyst and products are some benefits of this process.

Construction of new heteroacenes based on benzo[b]thieno[2,3-d] thiophene / quinoline or 1,8-naphthyridine systems using the Friedlander reaction

Two new classes of heteroacenes, namely benzo[4′,5′]thieno[2′,3′:4,5]thieno[3,2-b]quinolines and benzo [4′,5′]thieno[2′,3′:4,5]thieno[3,2-b][1,8]naphthyridines, have been formed using the Friedlander reaction to annulate the benzo[b]thieno[2,3-d]thiophene scaffold to quinoline or 1,8-naphthyridine fragments. In accordance with this synthetic strategy, benzo[b]thieno[2,3-d]thiophen-3(2H)-ones were treated with 2-aminobenzaldehydes or 2-aminonicotinaldehyde in the presence of pyrrolidine in glacial acetic acid at reflux to give the desired quinoline- or 1,8-naphthyridine-fused compounds, respectively. The optical and electrochemical properties of selected heteroacenes were determined. (C) 2019 Elsevier Ltd. All rights reserved.

Dinuclear oxidative addition reactions using an isostructural series of Ni-2, Co-2, and Fe-2 complexes

A family of low-valent Ni-2, Co-2, and Fe-2 naphthyridine-diimine (NDI) complexes is presented. Ligand-based pi* orbitals are sufficiently low-lying to fall within the metal 3d manifold, resulting in electronic structures that are highly delocalized across the conjugated [NDI]M-2 system. This feature confers stability to metalmetal interactions during two-electron redox reactions, as demonstrated in a prototypical oxidative addition of allyl chloride.

Multifaceted Coordination of Naphthyridine-Functionalized N-Heterocyclic Carbene: A Novel Ir-III(C boolean AND N)(C boolean AND C) Compound and Its Evaluation as Transfer Hydrogenation Catalyst

The 1,8-naphthyridine-functionalized N-heterocyclic carbene 1-benzyl-3-(5,7-dimethyl-1,8-naphthyrid-2-yl)imidazol-2-yl-idene (BIN) has been successfully coordinated to Pd(II), W(0), Rh(l), and Ir(III), exhibiting its diverse binding modes. Reaction of BIN center dot HBr with Ag2O, followed by transmetalation with PdCl2(COD)(2) provides a cis complex PdCl2(kC(2)-BIN)(2) (1). Treatment of BIN center dot HBr with W(CO)(4)(pipeddine)(2) in acetonitrile affords a chelate complex W(CO)(4)(k(2)C(2),N-1′-BIN) (2). Reaction of {RhCl(COD)}(2) with KOBu and subsequent treatment with BIN center dot HBr in 1:2 and 1:1 ratio results in the mono and dinuclear complexes [Rh(COD)Br(KC2-BIN)] (3) and [{Rh(COD)Br)(2)(KN8′:C-K(2)-BIN)] (4), respectively. In complex 3, the Rh(COD)Br unit is coordinated to the carbene center, whereas an additional Rh(COD)Br unit is attached to naphthyridine nitrogen in complex 4 in an anti arrangement. Under identical reaction condition, a novel Ir(III) complex [Ir((KC2)-C-2,N-1′-BIN)((KC3)-C-2′,C-2-BIN)(H2O)Br]Br (5) has been synthesized. Complex 5 is proved to be catalytically active in hydrogen transfer reaction from PrOH. All complexes have been characterized by spectroscopic methods and X-ray crystallography.

Design, Synthesis, and Biological Evaluation of 4-Quinoline Carboxylic Acids as Inhibitors of Dihydroorotate Dehydrogenase

We pursued a structure-guided approach toward the development of improved dihydroorotate dehydrogenase (DHODH) inhibitors with the goal of forming new interactions between DHODH and the brequinar class of inhibitors. Two potential residues, T63 and Y356, suitable for novel H-bonding interactions, were identified in the brequinar-binding pocket. Analogues were designed to maintain the essential pharmacophore and form new electrostatic interactions through strategically positioned H-bond accepting groups. This effort led to the discovery of potent quinoline-based analogues 41 (DHODH IC50 = 9.71 +/- 1.4 nM) and 43 (DHODH IC50 = 26.2 +/- 1.8 nM). A cocrystal structure between 43 and DHODH depicts a novel water mediated H-bond interaction with T63. Additional optimization led to the 1,7-naphthyridine 46 (DHODH IC50 = 28.3 +/- 3.3 nM) that forms a novel H-bond with Y356. Importantly, compound 41 possesses significant oral bioavailability (F = 56%) and an elimination t(1/2) = 2.78 h (PO dosing). In conclusion, the data supports further preclinical studies of our lead compounds toward selection of a candidate for early-stage clinical development.

Electronic and structural properties of N -> B-ladder boranes with high electron affinity

A series of new pi-conjugated N -> B-ladder boranes has been prepared in high yield by two-fold hydroboration of bifunctional quaterpyridine-, pyrimidine-, and 1,5-naphthyridine-based precursors with 9H-BBN and Piers’ borane ((C6F5)(2)BH). The structures of several ladder-boranes have been confirmed by X-ray crystallography, and their optical and electrochemical properties have been characterized, and complemented by DFT calculations. The electronic structure of the individual ladder boranes, as well as differences in the optical properties that originate from the chemical structure of the boryl-side-chains, are discussed. The results consistently show that, compared to the precursors, the optical gaps of the ladder boranes are significantly reduced, and the electron affinities are strongly increased to between -3.4 and -4.0 eV. Further investigations of chemically and electrochemically reduced species indicate that excess electrons in these kinds of systems are effectively delocalized throughout the conjugated systems.
