On June 22, 2022, Jia, Zongbin; Zhang, Long; Luo, Sanzhong published an article.Name: Methyl 2-cyclopentanonecarboxylate The title of the article was Asymmetric C-H Dehydrogenative Allylic Alkylation by Ternary Photoredox-Cobalt-Chiral Primary Amine Catalysis under Visible Light. And the article contained the following:
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 process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).Name: Methyl 2-cyclopentanonecarboxylate
The Article related to oxo allyl carboxylate preparation enantioselective, ketocarbonyl alkene dehydrogenative allylic alkylation cobalt photocatalyst, General Organic Chemistry: Synthetic Methods and other aspects.Name: Methyl 2-cyclopentanonecarboxylate
