A Sc(OTf)(3)-catalyzed cascade reaction of o-aminoacetophenone with methanamine: construction of dibenzo[b,h][1,6]naphthyridine derivatives

An unexpected Sc(OTf)(3)-catalyzed and air-mediated cascade reaction of o-aminoacetophenones with methanamines was discovered as an efficient synthetic approach to a novel class of fluorescent fused-four-ring dibenzo[b,h][1,6] naphthyridine derivatives. Two possible mechanisms of the reaction were proposed. The photophysical properties of the dibenzo[b,h][1,6]naphthyridine 1a were initially considered.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 2835-95-2. Name: 5-Amino-2-methylphenol.

Synthesis and characteristics of novel fluorescence dyes based on chromeno[4,3,2-de][1,6]naphthyridine framework

A series of entirely new framework chromeno[4,3,2-de][1,6]naphthyridine derivatives containing carbazole groups have been carefully designed and prepared. The relationship of photoluminescence property and structure of these compounds was systematically investigated via UV-vis, fluorescence and electrochemical analyzer. The HOMO and LUMO distributions of these compounds were calculated by density functional theory (DFT) (B3LYP; 6-31G*) method. These compounds exhibited high fluorescence quantum yields, desirable HOMO levels and high thermal stability, indicating that the combination of chromeno[4,3,2-de][1,6]naphthyridine and carbazole could be an efficient means to enhance hole-transporting ability and fluorescent quantum yield.

1,8-Naphthyridine-based boron complexes: visible colorimetric probes for highly selective sensing of phosphoric ion

Two 1,8-naphthyridine-based N,O-chelated boron complexes (1 and 2) were designed as novel phosphate ion (Pi) probes, which are based on a methoxy oxalyl group reaction site. These two probes showed high selectivity for Pi detection without interference from ATP, PPi, or other anions. Dramatic color changes from colorless to light yellow were observed by addition of Pi to solutions of 1 and 2 in DMSO/HEPES buffer (0.02 M, pH 7.4) (V/V = 8:2). This qualitative color shift was accompanied by red-shifts in the UV-vis absorbance spectrum of approximately 43 nm for 1 and 46 nm for 2. Fluorescence quenching was observed in solutions of I (Phi = 0.31) and 2 (Phi = 0.23) upon addition of Pi. Probes 1 and 2 are the first two 1,8-naphthyridine-based boron complexes developed which serve as colorimetric probes capable of highly selective detection of Pi over other phosphate-based chemical species including P2O74-, ATP, ADP, AMP, GTP, GDP, GMP, UP, TDP, TMP, UTP, UDP, and UMP. The in vivo imaging results demonstrate that 1 and 2 are able to permeate into the HeLa cells and Caenorhabditis elegans to detect Pi via a strong fluorescence intensity change.

Homoleptic mono- and dinuclear complexes of platinum(II) with 1,8-naphthyridine

Two unprecedented, homoleptic Pt-1,8-naphthyridine complexes have been prepared and characterized. Reaction between 1,8-naphthyridine (napy) and a platinum(II) precursor leads to a mononuclear homoleptic platinum(II) complex with stoichiometry [Pt(napy)(4)](OTf)(2). On the contrary, reaction between napy and a dinuclear platinum(III) precursor produces instead a rare example of a dinuclear, homoleptic, tetracationic platinum(II) complex with stoichiometry [Pt-2(napy)(4)](OTf)(4). Crystal structures of both complexes have been obtained. The redox behavior of the dinuclear complex has been studied by cyclic voltammetry, in order to establish its suitability as model precatalyst for organometallic reactions exploiting the Pt(II)/Pt(IV) or Pt(II)/Pt(III) manifold.

Synthesis, structures and spectroscopic properties of new 1,2-bis[2-(4-methyl-7-acetylamino-1,8-naphthyridine)]ethylene ligand and its binuclear copper(I) complexes

The synthesis, characterization, spectroscopic properties of a new ligand 1,2-bis[2-(4-methyl-7-acetyl-amino-1,8-naphthyridine)]ethylene (L) and its two binuclear Cu(I) complexes containing triphenylphosphine (PPh3) or bis(diphenylphosphino)methane (dppm), [Cu-2(L)(PPh3)(4)](BF4)(2)center dot 2CH(2)Cl(2) (1 center dot 2CH(2)Cl(2)) and [Cu-2(L)(dppm)(2)](BF4)(2)center dot 4H(2)O (2 center dot 4H(2)O) are reported. The structural investigation of these compounds based on X-ray crystal analysis shows that the copper(I) centers adopt different coordination geometries, O(N)CuP2+ and NCuP2+ for complexes 1 and 2, respectively. Upon irradiation of a degassed organic solution of L at 365 nm, photoinduced isomerization reaction and an intramolecular proton transfer of ligand L were detailed studied by absorption spectral changes. A spectroscopic investigation involving time-dependent density functional theory calculations allows assignment of the excited states that relate to emission and transient absorption spectra. The observed lower-energy absorption bands appearing in the region of 413 and 418 nm for 1 and 2 in dichloromethane are assigned to ligand-to-ligand charge transfer (LLCT, phosphine -> napy) transition in nature. Compared with well-structured solid-state emission originating from pi pi* transition of ligand L, complexes 1 and 2 exhibit intense room-temperature solid-state emissions with lambda(max) at 586 and 620 nm, respectively. The energy and the shape of the emission bands are clearly different from that of the ligand, indicating the emissions come from different excited states. (C) 2011 Elsevier B.V. All rights reserved.

Aaptodines A-D, Spiro Naphthyridine-Furooxazoloquinoline Hybrid Alkaloids from the Sponge Aaptos suberitoides

LC-MS-oriented fractionation of the sponge Aaptos suberitoides resulted in the isolation of four heptacyclic alkaloids, aaptodines A-D (1-4), which contain 9,10-dihydrofuro[2,3-f][1,3]oxazolo[5,4-h]-quinolone and 7,8-dihydrocyclopenta[de][1,6]naphthyridine subunits with a spiro carbon atom. The structures were determined on the basis of NMR spectroscopic and single-crystal X-ray diffraction data analysis aided by electronic circular dichroism calculations and Mosher’s method. A biosynthetic pathway for the formation of aaptodines A-D is postulated. Aaptodine D exhibits potent inhibition against osteoclast formation.

Spectroscopic Studies on the Interaction of Naphthyridines with DNA and Fluorescent Detection of DNA in Agarose Gel

Four new naphthyridine derivatives (R1-R4) possessing amino acid or boronic acid moieties have been synthesized and characterized using H-1 and C-13 NMR, FT-IR, and mass spectral techniques. The mechanism of binding of these probes with calf thymus DNA (CT-DNA) has been delineated through UV-Vis, fluorescence, and circular dichroism (CD) spectral techniques along with thermodynamic and molecular docking studies. Small hypochromicity in absorption maximum of the probes without any shift in wavelength of absorption suggests groove binding mode of interaction of these probes with CT-DNA, confirmed by CD and 1H NMR spectral data competitive binding assay with ethidium bromide (EB). CT-DNA quenches the fluorescence of these probes via a static quenching mechanism. In the case of R1 and R4, the observed Delta H-o < 0 and Delta S-o > 0suggest that these probes interact with CT-DNA through H-bonding and hydrophobic interactions, while in the interaction of R2 and R3, van der Walls and H-boding forces are found to be dominant (Delta H-o < 0 and Delta S-o < 0). Results of molecular docking investigations corroborate well with that of spectral studies, and these probes bind in the minor groove of DNA. These probes are found to be effective fluorescent staining agents for DNA in agarose gel in gel electrophoresis experiment with sensitivity comparable to that of EB, and DNA amounts as low as 37.5 ng are visually detectable in the gel. But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 38002-45-8, you can contact me at any time and look forward to more communication.

Hydrogen bonded supramolecular architectures of organic salts based on 5,7-dimethyl-1,8-naphthyridine-2-amine and acidic compounds

Studies concentrating on hydrogen bonding between the base of 5,7-dimethyl-1,8-naphthyridine-2-amine and acidic compounds have led to an increased understanding of the role 5,7-dimethyl-1,8-naphthyridine-2-amine has in binding with acidic compounds. Here anhydrous and hydrated multicomponent crystals of 5,7-dimethyl-1,8-naphthyridine-2-amine have been prepared with oxalic acid, 2,4,6-trinitrophenol, terephthalic acid, and phthalic acid. The four crystalline forms reported are organic salts of which the crystal structures have all been determined by X-ray diffraction. All products were formed in solution and obtained by the slow evaporation technique. The role of weak and strong hydrogen bonding in the crystal packing is ascertained.
