Lee, Sumin;Rovis, Tomislav research published 《 Rh(III)-Catalyzed Three-Component Syn-Carboamination of Alkenes Using Arylboronic Acids and Dioxazolones》, the research content is summarized as follows. A Rh(III)-catalyzed three-component carboamination of alkenes, e.g., 1,4-dihydro-1,4-epoxynaphthalene from readily available aryl boronic acids R¹B(OH)₂ (R¹ = C₆H₅, 1-naphthyl, 2H-1,3-benzodioxol-5-yl, etc.) as a carbon source and dioxazolones I (R² = CH₃, cyclopropyl, 2-cyclohexylethyl, etc.) as nitrogen electrophiles is described. This protocol provides facile access to valuable amine products including α-amino acid derivatives, e.g., II in good yield and regioselectivity without the need for a directing functionality. A series of experiments suggest a mechanism in which the Rh(III) catalyst undergoes transmetalation with the aryl boronic acid, followed by turnover limiting alkene migratory insertion into the Rh(III)-aryl bond. Subsequently, fast Rh-nitrene formation provides the syn-carboamination product selectively after reductive elimination and proto-demetalation. Importantly, the protocol provides three-component coupling products in preference to a variety of two-component undesired byproducts.

Li, Bo;Yang, Chenxin;Wang, Xinhao;Li, Guangwu;Peng, Wangwang;Xiao, Huiping;Luo, Shenglian;Xie, Sheng;Wu, Jishan;Zeng, Zebing research published 《 Synthesis and Structural Elucidation of Bisdibenzocorannulene in Multiple Redox States》, the research content is summarized as follows. An anti-folded bowl-shaped bisdibenzocorannulene (BDBC) featuring a new chair-cyclohexane-like hexagon as a bridge of two dibenzocorannulene moieties was reported. The neutral compound showed multiple redox-active properties and could be converted to the corresponding redox states through chem. reduction or oxidation Chem. reduction of BDBC by stoichiometric addition of metallic potassium in the presence of [18]crown-6 ether, provided a radical anion BDBC.^– and a dianion BDBC^2-, resp.; while chem. oxidation by silver hexafluoroantimonate(V), converted the neutral compound to an open-shell singlet diradical dication (BDBC^••)²⁺. The structural consequences of both electron-reduction and oxidation were closely related to the release of ring-strain of the bowl-shaped π-scaffold and imposed steric hindrance of the hexagonal bridge. In addition, the unusual open-shell nature of the dication could mainly be attributed to the changing of localized antiaromaticity in the closed-shell structure to delocalized character in the biradical, and thus the emergence of weakly bonded π-electrons.
