In 2022,Jia, Zongbin; Zhang, Long; Luo, Sanzhong published an article in Journal of the American Chemical Society. The title of the article was 《Asymmetric C-H Dehydrogenative Allylic Alkylation by Ternary Photoredox-Cobalt-Chiral Primary Amine Catalysis under Visible Light》.Recommanded Product: 609-14-3 The author mentioned the following in the article:
Herein, an asym. C-H dehydrogenative allylic alkylation by a synergistic catalytic system involving a chiral primary amine, a photoredox catalyst and a cobaloxime cocatalyst was reported. The ternary catalytic system enabled the coupling of β-ketocarbonyls and olefins to afford oxo(allyl)carboxylates with good yields and high enantioselectivities. Mechanism studies disclosed a cooperative radical addition process with a chiral α-imino radical and Co(II)-metalloradical wherein the chiral primary aminocatalyst and the cobaloxime catalyst work in concert to control the stereoinduction. The experimental part of the paper was very detailed, including the reaction process of Ethyl 2-methyl-3-oxobutanoate(cas: 609-14-3Recommanded Product: 609-14-3)
Ethyl 2-methyl-3-oxobutanoate(cas: 609-14-3) belongs to ketone compounds. They are most widely used as solvents, especially in industries manufacturing explosives, lacquers, paints, and textiles. Ketones are also used in tanning, as preservatives, and in hydraulic fluids.Recommanded Product: 609-14-3
