Abstract:
The title compound, C15H18N2O2S {systematic name: 6-[2-(cyclohexylsulfanyl)ethyl]-5H-pyrrolo[3,4-b]pyridine-5,7(6H)-dione}, was obtained from the reaction of pyridine-2,3-dicarboxylic anhydride (synonym: quinolinic anhydride) with 2-(cyclohexylsulfanyl)ethylamine. The dihedral angle between the mean plane of the cyclohexyl ring and the quinolinic acid imide ring is 25.43 (11)°. In the crystal, each molecule forms two C—H...O hydrogen bonds and one weak C—O...π [O...ring centroid = 3.255 (2) Å] interaction with neighbouring molecules to generate a ladder structure along theb-axis direction.

Abstract:
In this paper, some substituted imines compounds have been prepared from quinolinic acid as a starting material. Firstly, the quinolinic acid was treated with acetic anhydride and acetic acid to form furo[3,4-b]pyridine-5,7-dione (1); the resulting compound was heated with urea to form 5H-pyrrolo[3,4-b]pyridine-5,7(6H)-dione (2). After that, it was treated with potassium hydroxide to give potassium 5,7-dioxo-5,7-dihydropyrrolo[3,4-b]pyridin-6-dione, which was directly and easily converted to 6-(2-([1,1'-biphenyl]-4-yl)-2-oxoethyl)-5H-pyrrolo[3,4-b]pyridine-5,7(6H)-dione (3) by the reaction wit

AbstractThe mixed azines 3a–h and 4 were obtained by treating 3-hydrazonoindolin-2-one (2) with the appropriate aldehyde or dialdehyde. Treatment of 3b or 3c with formaldehyde or glutaric dialdehyde and the appropriate amine afforded the azine Mannich bases 5–7. The condensation of isatin or its N-Mannich base 8 with 1-aminopiperidine, 4-aminomorpholine and 1,4-diaminopiperazine gave 10a–d, 12 and 13.

AbstractThe compound 8-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-quinoline was prepared and found to hydrolyze rapidly in air; however, the expected product (quinolin-8-yl)boronic acid was not observed. Instead, the (quinolinium-8-yl)trihydroxyborate zwitterion or an anhydride were observed depending on the conditions of hydrolysis. The two products are related to one another in the degree of hydration, and the two forms could be interconverted. Both hydrolysis products were structurally characterized.

Reaction of 3-cyano-quinolin-2(1H)-thione (II) with ω-bromoacetophenones gave 3-amino-2-aroyl-thieno[2,3-b]quinolines (IVa-IVd). Whereas, interaction of II with chloroacetanilides yielded the corresponding thioesters Va-Vc which cyclized into 3-amino-2-arylcarbamoylthiene[2,3-b]quinolines (VIa-VIc) on treatment with ethoxide. Compounds VIa-VIc were reacted with nitrous acid, triethyl orthoformate and carbon disulfide to afford the fused polycyclic compounds VIIa-VIIc, VIIIa-VIIIc and IXa-IXc, respectively. Also treatment of IXa-IXc with ethyl iodide gave 3-ethylthio derivatives Xa-Xc. Moreover

A convenient two-step synthesis of ethyl 4-hydroxy-2-methylquinoline-3-carboxylate derivatives has been developed starting from commercially available 2-aminobenzoic acids. In step 1, the anthranilic acids are smoothly converted to isatoic anhydrides using solid triphosgene in THF. In step 2, the anhydride electrophiles are reacted with the sodium enolate of ethyl acetoacetate, generated from sodium hydroxide, in warm N,N-dimethylacetamide resulting in the formation of substituted quinolines.

Thus, acetylation of ethyl 3-(2-allylanilino)-3-phenylacrylate, (Ia), or ethyl 3-(2-allyl-4-methylanilino)-3-phenylacrylate, (Ib), with acetic anhydride yields not only the expected acetylated esters, (II), as the major products but also the unexpected polysubstituted quinolines 3-acetyl-8-allyl-2-phenylquinolin-4-yl acetate, (IIIa), and 3-acetyl-8-allyl-6-methyl-2-phenylquinolin-4-yl acetate, (IIIb), as

Abstract:
Carbonic Anhydrases (CAs, EC 4.2.1.1) are a family of monomeric Zinc metalloenzymes that catalyze the reversible hydration of CO2. The relevant role of this class of enzymes is the regulation of a broad range of physiological functions (gluconeogenesis, lipogenesis, and ureagenesis).[1] The family of human carbonic anhydrases (hCAs) comprises 15 different α-carbonic anhydrase isoforms: CA I-IV, CA VA and CA VB, CA VI-VII, CA IX, CA XII- XV and CARPs CA VIII, CA X, CA XI). In the last years, the attention toward this class of metalloproteins is in continuous growth because it was discovered th
