Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 70-23-5, is researched, SMILESS is O=C(OCC)C(CBr)=O, Molecular C5H7BrO3Journal, Article, Combinatorial Chemistry & High Throughput Screening called Green synthesis of 4H-pyran derivatives using Fe3O4-MNPs as efficient nanocatalyst: study of antioxidant activity, Author is Shafaei, Faezeh; Najar, Asef H., the main research direction is iron oxide magnetic nanoparticle preparation; dialkyl oxo dihydroindenopyran dicarboxylate green preparation antioxidant; ninhydrin haloketone dialkyl acetylenedicarboxylate triphenylphosphine multicomponent iron oxide nanocatalyst; Diels-Alder reactions; Fe3O4-MNPs; Ninhydrine; Pyran; green synthesis; α-haloketones.Recommanded Product: Ethyl 3-bromo-2-oxopropanoate.
A series of dialkyl 4-(oxo-alkoxy/aryl)-5-oxo-4,5-dihydroindeno[1,2-b]pyran-2,3-dicarboxylates I [R = CO2Et, 4-MeC6H4, 4-BrC6H4, etc.; R1 = Me, Et] was synthesized via a multicomponent reaction of ninhydrin, α-haloketones, dialkyl acetylenedicarboxylates and triphenylphosphine in the presence of iron oxide magnetic nanoparticles (Fe3O4-MNPs) as efficient nanocatalyst in ethanol at room temperature The biosynthesis of Fe3O4-MNPs was achieved using Clover Leaf water extract In addition, antioxidant activity was examined for some of the compounds I [R = CO2Et, 4-MeC6H4, 4-MeOC6H4, 4-O2NC6H4; R1 = Me, Et] employing DPPH radical scavenging and ferric reduction activity potential (FRAP) experiment and compared results with synthetic antioxidants (TBHQ and BHT). Compound I [R = CO2Et; R1 = Et] showed excellent radical trapping activity and good reducing activity relative to standards (BHT and TBHQ). Some advantages of this procedure were easiness of reaction workup and seperation of products by simply filtration. Fe3O4-MNPs displayed a good improvement in the yield of the product and showed significant reusable activity.
From this literature《Green synthesis of 4H-pyran derivatives using Fe3O4-MNPs as efficient nanocatalyst: study of antioxidant activity》,we know some information about this compound(70-23-5)Recommanded Product: Ethyl 3-bromo-2-oxopropanoate, but this is not all information, there are many literatures related to this compound(70-23-5).
