On August 10, 2020, Li, Longji; Li, Yao; Fu, Niankai; Zhang, Long; Luo, Sanzhong published an article.Formula: C7H10O3 The title of the article was Catalytic Asymmetric Electrochemical α-Arylation of Cyclic β-Ketocarbonyls with Anodic Benzyne Intermediates. And the article contained the following:
Asym. catalysis with benzyne remains elusive because of the highly fleeting and nonpolar nature of benzyne intermediates. Reported herein is an electrochem. approach for the oxidative generation of benzynes (cyclohexyne) and its successful merging with chiral primary aminocatalysis, formulating the first catalytic asym. enamine-benzyne (cyclohexyne) coupling reaction. Cobalt acetate was identified to stabilize the in situ generated arynes and facilitate its coupling with an enamine. This catalytic enamine-benzyne protocol provides a concise method for the construction of diverse α-aryl (α-cyclohexenyl) quaternary carbon stereogenic centers with good stereoselectivities. The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).Formula: C7H10O3
