In 2017,Qian, Ping; Deng, Yu; Mei, Haibo; Han, Jianlin; Pan, Yi published 《Metal-free nitroxyl radical-mediated β-C(sp3)-H amination of saturated ketones with heteroaryl halides: multiple roles of TEMPO》.Chemical Communications (Cambridge, United Kingdom) published the findings.Recommanded Product: 2-Chloro-1H-benzo[d]imidazole The information in the text is summarized as follows:
The first metal-free nitroxyl-radical-mediated β-amination of saturated ketones by using heteroaryl halides as amide precursors has been developed. This reaction proceeds through a cascade α-aminoxylation/Cope-like elimination/aza-Michael addition sequence to afford β-amino ketone derivatives with excellent yields. TEMPO plays multiple roles in the current β-amination process, including those of an oxidant, an α-aminoxylation reagent, a β-hydrogen acceptor, an in situ base, and an oxygen source. In the experiment, the researchers used many compounds, for example, 2-Chloro-1H-benzo[d]imidazole(cas: 4857-06-1Recommanded Product: 2-Chloro-1H-benzo[d]imidazole)
2-Chloro-1H-benzo[d]imidazole(cas: 4857-06-1) is an analog of benzimidazole that has been synthesized by Langmuir adsorption isotherm. It is a white crystalline solid that can be dissolved in water and hydrochloric acid. 2-Chloro-1H-benzo[d]imidazole inhibits the growth of herpes simplex virus by acting as a competitive inhibitor for the viral enzyme thymidine kinase, which catalyzes the conversion of thymine to thymidine.Recommanded Product: 2-Chloro-1H-benzo[d]imidazole
