Asahara, Haruyasu published the artcileSafe cyano(nitro)methylating reagent-Michael addition of cyano-aci-nitroacetate leading to δ-functionalized α-nitronitriles, Category: naphthyridine, the publication is Tetrahedron (2014), 70(37), 6522-6528, database is CAplus.

A practical, convenient, and safe cyano(nitro)methylation method was developed, in which cyano-aci-nitroacetate served as a synthetic equivalent of anionic nitroacetonitrile. A control of the single/double Michael additions was achieved, which enabled the synthesis of unsym. double Michael adducts. Moreover, the Michael adducts can be used as precursors of pyridine and naphthyridine frameworks.

Andrews, Michael published the artcileA luminescent rhenium(I) complex of 2,7-dimethyl-1,8-naphthyridine: Synthesis, spectroscopy and X-ray crystal structure, Category: naphthyridine, the publication is Transition Metal Chemistry (Dordrecht, Netherlands) (2009), 34(5), 493-497, database is CAplus.

2,7-Dimethyl-1,8-naphthyridine (L¹) reacts with pentacarbonylchlororhenium in toluene or chloroform to give the target complex fac-{ReCl(CO)₃(L¹)}. X-ray crystallog. data were obtained for fac-{ReCl(CO)₃(L¹)}. The structural and ¹H NMR data suggest that the ligand coordinates to the rhenium in a bidentate fashion in both solid and solution states. The complex also is luminescent in both solution and solid states. The fluxionality of the ligand in solution causes ligand-centered emission to be observed in solution, whereas only ³MLCT emission was observed in the solid state. Although the complex was air-stable, the lability of L¹ was studied in ¹H NMR experiments where CD₃OD induced complete ligand dissociation over 24 h, and also in reaction of fac-{ReCl(CO)₃(L¹)} with one equivalent of 2,2′-bipyridine in chloroform which resulted in quant. ligand exchange.

Patra, Kamaless published the artcileA Protic Mn(I) Complex Based on a Naphthyridine-N-oxide Scaffold: Protonation/Deprotonation Studies and Catalytic Applications for Alkylation of Ketones, Category: naphthyridine, the publication is Organometallics (2022), 41(14), 1836-1846, database is CAplus.

A Mn(I) complex (1) bearing a proton responsive hydroxy unit on 1,8-naphthyridine-N-oxide scaffold (L¹H) was synthesized. The mol. structure of 1 revealed the lactim form of the ligand. The corresponding deprotonated lactam complexes [18-C-6-K路2] and 3 were prepared and structurally characterized. The acid-base equilibrium between the lactim and lactam forms was studied by ¹H NMR and UV-visible spectra. The catalytic efficiency of 1 was evaluated by performing 伪-alkylation reaction of ketones with primary alcs. The scope of the 伪-alkylation reaction is broad in terms of both ketones and alcs. The efficacy of the protic catalyst is demonstrated in the alkylation of the bioactive steroids progesterone and pregnenolone. A controlled catalyst [Mn(L²)(CO)₃Br] (4), which is structurally similar to 1 but devoid of the proton responsive hydroxy unit, shows significantly reduced catalytic efficiency validating the crucial role of the hydroxy functionality in 1. Kinetic study, control reactions, and D labeling experiments were conducted to gain mechanistic insights.

Raj Sinha, Deo published the artcileNaphthyridines reactivity of methyl groups: new cyanine dyes from 2,7-dimethyl- and 4,7-dimethyl-1,8-naphthyridines, Quality Control of 14903-78-7, the publication is Journal of the Indian Chemical Society (1979), 56(2), 164-7, database is CAplus.

The reactivity of the 4-Me in 4,7-dimethyl-1,8-naphthyridine (I) [14759-23-0] is greater than the 7-Me towards condensation with m-nitrobenzladehyde [99-61-6]. Cyanine and styryl dyes derived from I and from 2,7-dimethyl-1,8-naphthyridine [14903-78-7] were prepared and their structures established. The trimethine dyes were found to be useless as sensitizers for Ag halide emulsions.

New crown compounds, e.g., I, comprising, beside o-phenylene groups, 1,8-naphthyridine or 4-pyridone groups as characteristic building units are synthesized. They form numerous stoichiometric crystalline complexes with uncharged organic mols. including alcs., nitro compounds and other dipolar-aprotic solvents, as well as cyclic ethers and aromatic hydrocarbons. Properties of complex formation and host-guest stoichiometries are discussed in comparison with parent host analogs.
