Domino Direct Arylation and Cross-Aldol for Rapid Construction of Extended Polycyclic π-Scaffolds was written by Nitti, Andrea;Bianchi, Gabriele;Po, Riccardo;Swager, Timothy M.;Pasini, Dario. And the article was included in Journal of the American Chemical Society in 2017.Synthetic Route of C10H11BrO2 This article mentions the following:

Five-membered aromatic heterocycles are a ubiquitous skeleton of π-conjugated organic compounds, and their incorporation requires synthetic protocols that are not easily industrially sustainable or scalable. Improved methodologies for their insertion into π-scaffolds are therefore necessary. We report an efficient and scalable protocol involving a one-pot cross-Aldol direct arylation reaction protocol for the rapid construction of thiophene- and furan-based π-extended organic materials. In the experiment, the researchers used many compounds, for example, Ethyl (2-bromophenyl)acetate (cas: 2178-24-7Synthetic Route of C10H11BrO2).

Ethyl (2-bromophenyl)acetate (cas: 2178-24-7) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon–bromine bond is electrophilic in nature. In the pharmaceutical industry organo bromine derivatives are used as sedatives, vasodilators, antiseptic agents, and anticancer agents.Synthetic Route of C10H11BrO2

Customized Buchwald-type phosphines bearing an “inverted” pyrimidinium betaine as an aryl group surrogate – synthesis and coordination chemistry with gold(I) was written by Noel-Duchesneau, Ludovik;Lugan, Noel;Lavigne, Guy;Labande, Agnes;Cesar, Vincent. And the article was included in European Journal of Inorganic Chemistry in 2015.Quality Control of Ethyl (2-bromophenyl)acetate This article mentions the following:

A new ligand scaffold I (1, R = ⁱPr) inspired by Buchwald-type phosphines is disclosed. Its design consists of the formal replacement of the distal aryl group of the original archetype by a pyrimidinium betaine connected to the o-phosphinophenyl moiety through the C-5 position of its malonate subunit. A productive synthetic pathway towards this phosphine is described along with its ability to coordinate to a gold(I) center. A weak bonding interaction between the metal center and the malonate group is observed in the solid state. In the experiment, the researchers used many compounds, for example, Ethyl (2-bromophenyl)acetate (cas: 2178-24-7Quality Control of Ethyl (2-bromophenyl)acetate).

Ethyl (2-bromophenyl)acetate (cas: 2178-24-7) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Quality Control of Ethyl (2-bromophenyl)acetate

New effective inhibitors of the Abelson kinase was written by Kraus, George A.;Gupta, Vinayak;Mokhtarian, Marjan;Mehanovic, Samir;Nilsen-Hamilton, Marit. And the article was included in Bioorganic & Medicinal Chemistry in 2010.Related Products of 2178-24-7 This article mentions the following:

The effects of substituents on the aryl ring were studied by the preparation and testing of several PD173955 analogs. Inserting a single carbon atom into the C-N bond in the aniline subunit (PDC) reduced the kinase inhibition by a factor of 200. Despite its decreased affinity for Abl compared with PD173955, PDC exhibits a Ki very similar to that reported for Imatinib. Increased water solubility is also gained by replacing the thiomethyl group with an amino or glycyl moiety. For both PD173955 and PDC, the analogs with amino groups in place of the methylthio group are 10 times more inhibitory than the parent mols. Two mols. were identified with Kis about three orders of magnitude lower than reported for Imatinib. In the experiment, the researchers used many compounds, for example, Ethyl (2-bromophenyl)acetate (cas: 2178-24-7Related Products of 2178-24-7).

Ethyl (2-bromophenyl)acetate (cas: 2178-24-7) belongs to organobromine compounds. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Related Products of 2178-24-7

An iron(II)-based metalloradical system for intramolecular amination of C(sp²)-H and C(sp³)-H bonds: synthetic applications and mechanistic studies was written by Das, Sandip Kumar;Das, Subrata;Ghosh, Supratim;Roy, Satyajit;Pareek, Monika;Roy, Brindaban;Sunoj, Raghavan B.;Chattopadhyay, Buddhadeb. And the article was included in Chemical Science in 2022.Recommanded Product: Ethyl (2-bromophenyl)acetate This article mentions the following:

A catalytic system for intramol. C(sp²)-H and C(sp³)-H amination of substituted tetrazolopyridines was successfully developed. The amination reactions were developed using an iron-porphyrin based catalytic system. It was demonstrated that the same iron-porphyrin based catalytic system efficiently activates both the C(sp²)-H and C(sp³)-H bonds of the tetrazole as well as azide-featuring substrates with a high level of regioselectivity. The method exhibited an excellent functional group tolerance. The method afforded three different classes of high-value N-heterocyclic scaffolds. A number of important late-stage C-H aminations were performed to access important classes of mols. Detailed studies (exptl. and computational) showed that both the C(sp²)-H and C(sp³)-H amination reactions involve a metalloradical activation mechanism, which is different from the previously reported electro-cyclization mechanism. Collectively, this study reports the discovery of a new class of metalloradical activation modes using a base metal catalyst that should find wide application in the context of medicinal chem., drug discovery and industrial applications.
