A 4-HO-TEMPO-catalyzed redox strategy for the synthesis of pyridines through the annulation of cyclopropanols and oxime acetates has been developed. This protocol features good functional group tolerance and high chemoselectivity and also promises to be efficient for the late-stage functionalization of skeletons of drugs and natural products. Mechanism studies indicate that the reaction involves the in situ generated alpha,beta-unsaturated ketones and imines as the key intermediates, which are derived from cyclopropanols and oxime acetates via a TEMPO/TEMPOH redox cycle, respectively. The pyridine products are formed as a result of annulation of enones with imines followed by TEMPO-catalyzed oxidative aromatization by excess oxime acetates. This method not only realizes the TEMPO-catalyzed redox reaction but also broadens the frontiers for TEMPO in catalysis.

Name: 1-(4-Nitrophenyl)ethanone. I found the field of Chemistry very interesting. Saw the article Selective hydrogenation of nitroaromatics toN-arylhydroxylamines in a micropacked bed reactor with passivated catalyst published in 2020.0, Reprint Addresses Yu, ZQ; Su, WK (corresponding author), Zhejiang Univ Technol, Natl Engn Res Ctr Proc Dev Act Pharmaceut Ingredi, Collaborat Innovat Ctr Yangtze River Delta Reg Gr, Hangzhou 310014, Peoples R China.; Su, WK (corresponding author), Zhejiang Univ Technol, Coll Pharmaceut Sci, Key Lab Green Pharmaceut Technol & Related Equipm, Minist Educ, Hangzhou 310014, Peoples R China.. The CAS is 100-19-6. Through research, I have a further understanding and discovery of 1-(4-Nitrophenyl)ethanone.

In this contribution, a protocol was established for the selective catalytic hydrogenation of nitroarenes to the correspondingN-arylhydroxylamines. The reduction of 1-(4-chlorophenyl)-3-((2-nitrobenzyl)oxy)-1H-pyrazole, an intermediate in the synthesis of the antifungal reagent pyraclostrobin that includes carbon-chlorine bonds, benzyl groups, carbon-carbon double bonds and other structures that are easily reduced, was chosen as the model reaction for catalyst evaluation and condition optimization. Extensive passivant evaluation showed that RANEY (R)-nickel treated with ammonia/DMSO (1 : 10, v/v) afforded the optimal result, especially with a particle size of 400-500 mesh. To combine the modified catalyst with continuous-flow reaction technology, the reaction was conducted at room temperature, rendering the desired product with a conversion rate of 99.4% and a selectivity of 99.8%. The regeneration of catalytic activity was also studied, and an in-column strategy was developed by pumping the passivate liquid overnight. Finally, the generality of the method was explored, and 7 substrates were developed, most of which showed a good conversion rate and selectivity, indicating that the method has a certain degree of generality.
