We reveal here a direct autoxidative phosphorylation of heteroarenes induced by oxygen under metal-free and solvent-free conditions. This new methodology provides an economical, operationally simple, and environmentally friendly approach toward (Het)C(sp2)-P formation with medium to excellent yields. Heteroarenes including thiazole and quinoxaline derivatives are applicable under standard conditions, which is testified via a radical mechanism.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Safety of 2-Chloroquinoxaline, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1448-87-9, in my other articles.

The preclinical characterization of novel octahydropyrrolo[3,4-c]pyrroles that are potent and selective orexin-2 antagonists is described. Optimization of physicochemical and DMPK properties led to the discovery of compounds with tissue distribution and duration of action suitable for evaluation in the treatment of primary insomnia. These selective orexin-2 antagonists are proven to promote sleep in rats, and this work ultimately led to the identification of a compound that progressed into human clinical trials for the treatment of primary insomnia. The synthesis, SAR, and optimization of the pharmacokinetic properties of this series of compounds as well as the identification of the clinical candidate, JNJ-42847922 (34), are described herein.

Computed Properties of C8H5ClN2, New research progress on 1448-87-9 in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 1448-87-9, Name is 2-Chloroquinoxaline, molecular formula is C8H5ClN2.

As part of our program aimed at the development of potent excitatory amino acid antagonists, we synthesized and evaluated a series of substituted 1,2,4- triazolo[4,3-a]quinoxalin-4(5H)-ones, 4, tetrazolo[1,5-a]quinoxalin-4(5H)- ones, 5, and pyrazolo[1,5-c]quinazolin-5(6H)-ones, 6, and an imidazo[1,2- a]quinoxalin-4(5H)-one, 7. In general, the same heterocycles which demonstrated the best affinity for the AMPA receptor also demonstrated the best affinity for the glycine site on the NMDA receptor complex. 1-Propyl- 7,8-dichloro-1,2,4-triazolo[4,3-a]quinoxalin-4(5H)-one, 4d, was found to bind with the greatest affinity to the AMPA receptor with an IC50 of 0.83 muM and antagonized 40 muM AMPA-induced depolarization in the cortical slice preparation with an IC50 of 44 muM. 7,8-Dichloro-1,2,4-triazolo[4,3- a]quinoxalin-4(5H)-one, 4a, and 7,8-dichloroimidazo[1,2-a]quinoxalin-4(5H)- one, 7, possessed the best affinity for the glycine site with IC50 values of 0.63 and 1.26 muM, respectively. It is noteworthy that the SAR for the heterocyclic compounds did not directly parallel that of known quinoxalinediones (e.g. DNQX, 2, and DCQX, 15) at the AMPA receptor nor that of the kynurenic acids at the glycine site on the NMDA receptor complex.

The oxidative magnesiation of nitrogen-containing pi-deficient halogenoheteroaromatics using active magnesium was accomplished. Both magnesiation followed by addition of a carbonyl compound (Grignard reaction) and magnesiation in the presence of a carbonyl compound (Barbier reaction) were carried out to afford the corresponding product. Especially, the latter method enabled fused halogenodiazines such as 4-chloro-1-phenyl-1H-pyrazolo[3,4-d]pyrimidine or 2-chloroquinoxaline to magnesiate at a mild temperature (-20 to 30 C).
