So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Savari, Mehdi; Varasteh-Moradi, Ali; Sayyed-Alangi, S. Zahra; Hossaini, Zinatossadat; Zafarmehrabian, Ramin researched the compound: Ethyl 3-bromo-2-oxopropanoate( cas:70-23-5 ).COA of Formula: C5H7BrO3.They published the article 《Ag/Fe3O4/TiO2@MWCNTs as a reusable organometallic nanocatalyst promoted green synthesis of new pyridobenzoazepines: Study of biological activity and reduction of organic pollutants》 about this compound( cas:70-23-5 ) in Applied Organometallic Chemistry. Keywords: magnetic nanocatalyst preparation; pyridobenzoazepine green preparation antibacterial radical scavenger antioxidant; isatoic anhydride alpha haloketone alkyne epoxide magnetic nanocatalyst multicomponent. We’ll tell you more about this compound (cas:70-23-5).
In this research, Ag/Fe3O4/TiO2@MWCNTs magnetic nanocomposites synthesized using water extract of Spinacia oleracea leaves, and the high performance of synthesized catalyst was confirmed by employing it in the multicomponent reaction of isatoic anhydride, N-methylimidazole, α-haloketones, electron-deficient acetylenic compounds, ammonium acetate, and Me epoxide in water at ambient temperature for the preparation of new pyridobenzoazepine derivatives such as I [X = H, Me, NO2, etc.; R1 = Me, Et; R2 = CO2Et, 4-MeC6H4, 4-MeOC6H4, etc.] in high yields. Also, the catalytic activity of the green synthesized Ag/Fe3O4/TiO2@MWCNTs was evaluated in the reduction of organic pollutants such as 4-nitrophenol in water at mild conditions. The results indicated that the biosynthesized magnetic nanocomposites (MNCs) have very high and effective catalytic activity for organic pollutants within few seconds. The synthesized compounds have OH group in their structure and for this reason might be showed good antioxidant activity. Also, employing Gram-pos. and Gram-neg. bacteria in the disk diffusion procedure confirmed antimicrobial effect of the some pyridobenzoazepine derivatives The results showed that synthesized compounds prevented the bacterial growth. This used procedure for preparation of pyridobenzoazepine derivatives have some advantages such as low reaction time, product with high yields, and simple separation of catalyst and products.
After consulting a lot of data, we found that this compound(70-23-5)COA of Formula: C5H7BrO3 can be used in many types of reactions. And in most cases, this compound has more advantages.
