Grafting of -aminobutyric acid on the superparamagnetic -Fe2O3@SiO2 nanoparticles afforded -Fe2O3@SiO2–aminobutyric acid as a novel heterogeneous nanocatalyst, which was characterized by X-ray diffraction, Fourier transform-infrared spectroscopy, vibrating sample magnetometry, field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, and thermal analysis. In this research, we report a convenient and one-pot efficient direct protocol for the pseudo four-component preparation of chromeno[4,3,2-de][1,6]naphthyridine derivatives via cascade condensation reaction of malononitrile, 2,4-dihydroxyacetophenone with various aromatic aldehydes in the presence of the catalytic amount of the -Fe2O3@SiO2–aminobutyric acid under green conditions in aqueous media. This procedure offers several advantages such as: very easy reaction conditions, simple work-up, or purification, excellent yields, high purity of the desired product, atom economy, and short reaction times. The superparamagnetic nanocatalyst is magnetically separable and kept stability after recycling for at least five consecutive runs without detectable activity loss. [GRAPHICS] .

New Advances in Chemical Research, April 2021.The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 63503-60-6, Name is 3-Chlorophenylboronic acid, SMILES is ClC1=CC=CC(=C1)B(O)O, belongs to naphthyridine compound.

Several novel fluorogenic N-aminoacylnaphthyridine substrates were synthesized in good yield and tested for their ability to detect pathogenic bacteria in agar-based cell culture. Simple 2-N-(beta-alanyl)amino-5,7-dialkylnaphthyridine substrates were selectively hydrolysed by beta-alanylaminopeptidase expressing bacteria, but were subject to diffusion in the agar medium. Diffusion was reduced in the 2-N-(beta-alanyl)amino-7-alkylnaphthyridine substrates with longer alkyl chains, but inhibition of growth was increased. 2-N-(beta-Alanyl)amino-7-octylnaphthyridine inhibited the growth of all species tested, except for strains resistant to colistin/polymyxin, providing a rationale for the development of substrates for the selective detection of drug resistant species in clinical samples.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. If you like, you can also browse other articles about this kind.

n-Alkyllithiums were added to alpha,alpha’-disubstituted-1,8-naphthyridines in non-polar solvents Such as Et2O-hexane mixtures. In polar solvents such as THF, alkyllithium acts as a base rather than a nucleophile. Regioselective addition was achieved for substrates capable of five-membered cyclic chelation of the (alkyl)lithium reagent. Substrates with a TBS-protected alcohol as the co-chelating moiety afforded the best combination of yield and regioselectivity. This methodology was Successfully employed in the preparation of two 6-amino-3-pyridinol analogs of pentamethyl-chromanol (PMC), an alpha-tocopherol derivative with its isoprenoid side chain truncated to a methyl group.

This review covers the synthesis and reactivity of 1,5-naphthyridine derivatives published in the last 18 years. These heterocycles present a significant importance in the field of medicinal chemistry because many of them exhibit a great variety of biological activities. First, the published strategies related to the synthesis of 1,5-naphthyridines are presented followed by the reactivity of these compounds with electrophilic or nucleophilic reagents, in oxidations, reductions, cross-coupling reactions, modification of side chains or formation of metal complexes.

Two TADF emitters 2,7-di(9H-carbazole)-1,8-naphthyridine (Cz-ND) and 2,7-di(3,6-di-tert-butyl-9H-carbazole)-1,8-naphthyridine (tBuCz-ND) were designed and synthesized. Both of the emitters showed high thermal stabilities and strong blue emissions with high photoluminescence quantum yields, and also exhibited excellent TADF properties with small Delta E-ST values. Consequently, blue organic light-emitting diodes (OLEDs) based on Cz-ND and tBuCz-ND were fabricated, which could achieve maximum external quantum efficiencies (EQE(max)) of 15.3 and 20.9%, respectively. Moreover, the devices also exhibited relatively narrow band gaps at 79 and 75 nm with the CIE coordinates of (0.15, 0.17) and (0.15, 0.22), respectively.
