Cocrystallization of the aromatic bronsted bases with a series of mineral acids gave a total of ten hybrid salts with the compositions: (2-methylquinoline)2: (hydrochloride acid): 3H(2)O [(HL1)(+)center dot(L1)..(Cl-)center dot(H2O)(3)] (1), (6-bromobenzo[d]thiazol-2-amine): (hydrochloride acid) [(HL2)(+)center dot(Cl-)] (2), (6-bromobenzo[d]thiazol-2amine): (nitric acid) [(HL2)(+)center dot(NO3-)] (3), (6-bromobenzo[d]thiazol-2-amine): (sulfuric acid) [(HL2)(+)center dot (HSO4)(-)] (4), (6-bromobenzo[d]thiazol-2-amine): (phosphoric acid) [(HL2)(+)center dot(H2PO4)(-)] (5), (5,7-dimethy11,8-naphthyridine-2-amine): (hydrochloride acid): 3H(2)O[(HL3)(+)center dot(Cl-) (H2O)(3)] (6), (5,7-dimethyl-1,8naphthyridine-2-amine): (hydrobromic acid): CH3OH [(HL3)(+)center dot(Br)(-)center dot CH3OH] (7), (5,7-dimethyl-1,8naphthyridine-2-amine): (sulfuric acid): H2O [(HL3)(+)center dot(HSO4)(-)center dot H2O] (8), (2-aminophenol): (phosphoric acid) [(HLA)(+)center dot(H2PO4)(-)] (9), and (2-amino-4-chlorophenol): (phosphoric acid) [(HL5)(+)center dot(H2PO4)(-)] (10). The ten salts have been characterized by X-ray diffraction analysis, IR, and elemental analysis, and the melting points of all the salts were also reported. And their structural and supramolecular aspects are fully analyzed. The result reveals that among the ten investigated crystals the ring N of the heterocycle or the NH2 in the aminophenol are protonated when the acids are deprotonated, and the crystal packing is interpreted in terms of the strong charge-assisted classical hydrogen bonds between the NH+/NH3+ and deprotonated acidic groups. Further analysis of the crystal packing of the salts indicated that a different family of additional CH-O, CH-Cl, CH3-N, CH3-O, CH-Br, CH3-Br, Br-CI, Cl-S, O-S, O-O, Br-S, H-H, and pi-pi associations contribute to the stabilization and expansion of the total high-dimensional frameworks. For the coexistence of the various weak nonbonding interactions these structures adopted homo or hetero supramolecular synthons or both. Some classical supramolecular synthons, such as R-2(2)(8), R-4(2)(8), R-4(3)(10) and R-4(4)(12), usually observed in the organic solids, were again shown to be involved in constructing most of these H-bonding networks.

2-Amino-7-chloro-1,8-napthyridine (1) undergoes condensation with different aromatic aldehydes to form 2-arylideneamino-7-chloro-1,8-naphthyridines (2-6). These imines when treated with different reagents varied substituted derivatives are produced. Compounds 2-6 are converted to different dyes (7-11) by diazotization. Azetidinones (12-16) are obtained by the reaction of 2-6 and chloroacetylehloride in presence of triethylamine. Finally the imines are converted to thiazolidinones (17-21) by treating compounds with thinglycolic acid.

Chemical Research Letters, April 2021. Synthetic Route of 13922-41-3, In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 13922-41-3, Name is Naphthalen-1-ylboronic acid, SMILES is C1=CC=C2C(=C1)C(=CC=C2)B(O)O, belongs to naphthyridine compound.

An expanded GGGGCC hexanucleotide (G(4)C(2)) repeat within the non-coding region of C9ORF72 gene has been identified as the most common genetic cause of FTD/ALS kindred, and synthetic ligand targeting this pathological expansion sequence holds a promising approach for the disease interference. We here describe the naphthyridine carbamate tetramer, p-NCTB, as a binding ligand to hairpin G(4)C(2) repeat. p-NCTB simultaneously recognizes two distal CGGG/CGGG sites in G4C2 repeat DNA and RNA leading to the formation of the interhelical (inter-and intrastrand) binding complexes. The intrastrand binding was predominant when p-NCTB bound to long repeat sequence that accommodates multiple binding sites by folding into hairpins, while the interstrand binding was exclusive for short repeat sequence. The binding of p-NCTB showed repeat-length selectivity: the longer repeat sequence is a better target for p-NCTB. p-NCTB demonstrated inhibition of transcription against G(4)C(2) repeat template in vitro in a repeat length-dependent manner.

In each of them, the coordinate geometry of Cu atom is a distorted square planar configuration with bond distances and angles in the normal range. Moreover, compound 2 features one-dimensional zigzag chains which are cross-linked by the metal complex cations and PF6- anions through hydrogen bonding interactions. The HOMO-LUMO energy gaps of 1-2 estimated by the cyclic voltammetry (CV) show values in the order of 1 > 2. Both 1 and 2 show low-energy bands ranging from 360 to 430 nm and available florescence in the solid state at room temperature with lambda(max) = 532-541 nm. The UV-vis absorption spectra of 1-2 show obvious red-shifts compared with those of the corresponding quinoline containing Cu(I) complexes [Cu(QN)(2)]PF6 (QN = 8-diphenylphosphino quinoline), exhibiting the HOMO-LUMO energy gaps of 1-2 should be narrower than that of [Cu(QN)(2)]PF6.

Thiazinanes and its isomeric forms represent one of the most important heterocyclic compounds, and their derivatives represented a highly potent drug in disease treatment such as, 1,1-dioxido-1,2-thiazinan-1,6-naphthyridine, which has been shown to have anti-HIV activity by a mechanism that should work as anti-AIDS treatment, while (Z)-methyl 3-(naphthalen-1-ylimino)- 2-thia-4-azaspiro[5 5]undecane-4-carbodithioate showed analgesic activity, cephradine was used as antibiotic and chlormezanone was utilized as anticoagulants. All publications were interested in the chemistry of thiazine (partially or fully unsaturated heterocyclic six-membered ring containing nitrogen and sulfur), but no one was dealing with thiazinane itself which encouraged us to shed new light on these interesting heterocycles. This review was focused on the synthetic approaches of thiazinane derivatives and their chemical reactivity.

A series of new poly-functionalized fused naphthyridine derivatives were synthesized via a three-component reaction of aldehyde, 2-aminoprop-1-ene-1,1,3-tricarbonitrile and enaminone in EtOH using EtONa as a base. During these reaction processes, the domino construction of fused naphthyridine skeleton with concomitant formation of two new pyridine rings was readily achieved via base promoted three-component reactions in a one-pot operation. The procedures are facile, avoiding time-consuming and costly syntheses, tedious work-up and purifications of precursors.
