Azastilbenes. 1. Synthesis, Characterization, and Structure

The synthesis of several symmetric and asymmetric azastilbenes is described, and their spectral characteristics (NMR, mass, UV, IR) are given.Four of them are new compounds, namely, 1,2-di(4-isoquinolyl)ethylene, 1-(3-pyridyl)-2-(2-pyrazinyl)ethylene, 1-(3-pyridyl)-2-(4-isoquinolyl)ethylene, and 1-(2-pyrazinyl)-2-(4-isoquinolyl)ethylene.The molecular structure and crystalline stacking of some of these azastilbenes and of the quaternary salts of 1,2-di(2-pyridyl)ethylene and 1,2-di(4-pyridyl)ethylene have been determined by X-ray diffraction on a single crystal and their characteristic parameters indicated.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 22960-16-3 is helpful to your research. Application of 22960-16-3

Fates of imine intermediates in radical cyclizations of N-sulfonylindoles and ene-sulfonamides

Two new fates of imine intermediates formed on radical cyclizations of ene-sulfonamides have been identified, reduction and hydration/fragmentation. Tin hydride-mediated cyclizations of 2-halo-N-(3-methyl-N-sulfonylindole)anilines provide spiro[indo-line-3,3?-indolones] or spiro-3,3?-biindolines (derived from imine reduction), depending on the indole C2 substituent. Cyclizations of 2-haloanilide derivatives of 3-carboxy-N-sulfonyl-2,3-dihydropyrroles also presumably form spiro-imines as primary products. However, the lactam carbonyl group facilitates the ring-opening of these cyclic imines by a new pathway of hydration and retro-Claisen-type reaction, providing rearranged 2-(2?-formamidoethyl)oxindoles.

Electrophotocatalytic C-H Functionalization of Ethers with High Regioselectivity

The highly regioselective electrophotocatalytic C-H functionalization of ethers is described. These reactions are catalyzed by a trisaminocyclopropenium (TAC) ion at mild electrochemical potential with visible light irradiation. Ethers undergo oxidant-free coupling with isoquinolines, alkenes, alkynes, pyrazoles, and purines with typically high regioselectivity for the less-hindered alpha-position. The reaction is proposed to operate via hydrogen atom transfer (HAT) from the substrate to the photoexcited TAC radical dication, thus demonstrating a new reactivity mode for this electrophotocatalyst.

N-oxidation of 2-substituted pyridines and quinolines by dimethyldioxirane: Kinetics and steric effects

The oxidation of 2-substituted pyridines and selected N-containing aromatic heterocycles by dimethyldioxirane (1) produced the corresponding N-oxides as the sole products, quantitatively in most cases. The second order rate constants for N-oxidation by 1 in dried acetone at 23C were determined for a series of 2-substituted pyridines 2-10, quinolines 11-14 and isoquinolines 15,16. An excellent correlation of log k2 with Taft (sigma*) constants was obtained for 2-substituted pyridines (R = Me, Et, Prn, Pr i, 3-pentyl) with the exception of the data for 2-f-butylpyridine. The results for the substituted quinolines and isoquinolines followed the same trends observed with the pyridines. Steric effects due to 2-substitution and periinteractions can substantially reduce reactivity. The results provide insights into the geometrical requirements for N-oxidation by dimethyldioxirane.

Synthesis of pyrido[2,1-a]isoquinolin-4-ones and oxazino[2,3-a]isoquinolin- 4-ones: New inhibitors of mitochondrial respiratory chain

Benzo[a]quinolizine is an important heterocyclic framework that can be found in numerous bioactive compounds. The general scheme for the synthesis of these compounds was based on the preparation of the appropriate dihydroisoquinolines by Bischler-Napieralski cyclization with good yields, followed by the Pemberton method to form the oxazinones or pyridones derivatives via acyl-ketene imine cyclocondensation. All the synthesized compounds were assayed in vitro for their ability to inhibit mitochondrial respiratory chain. Most of the tested compounds were able to inhibit the integrated electron transfer chain, measured as NADH oxidation, which includes complexes I, III and IV, in the low micromolar range. Oxazino[2,3-a]isoquinolin-4-ones displayed greater activity than their pyrido[2,1-a]isoquinolin-4-ones analogs. Indeed, the presence of a furan ring in C2 position of oxazino[2,3-a] isoquinolin-4-ones provided the compound (1g) with the most potent biological activity. Therefore, these compounds and especially the oxazinone derivatives are in the tendency of the new less toxic antitumor agents that target mitochondrial electron transport chain in a middle range potency.
