Highly γ-selective and enantioselective insertion into N-H bonds of aliphatic or aromatic secondary amines with vinyl substituted α-diazo pyrazoleamides using a high-spin chiral N,N’-dioxide/cobalt(II) complex catalyst. The method afforded a wide variety of valuable optically active Z- and E-type vinyl γ-amino amides. Calculation revealed a spin state change from the quartet cobalt(II) complex to a doublet Co(II)-carbene species for facile Z-selective and enantioselective nucleophilic addition

Kreisel, Tatjana published the artcileModular Generation of (Iodinated) Polyarenes Using Triethylgermane as Orthogonal Masking Group, Safety of 4-Methoxy-N-methylaniline, the main research area is polyarene preparation; triethylgermane preparation; aryl halide preparation; Chemoselectivity; Modular Couplings; Organogermanes; Palladium(I) Dimers; Polyarenes.

Herein, a complementary modular coupling approach to the widely employed Suzuki coupling strategy of boron containing precursors, which relied on organogermane containing building blocks as key orthogonal functionality and an electrophilic (rather than nucleophilic) unmasking event paired with air-stable PdI dimer based bond construction was disclosed. This allowed to significantly shorten the reaction times for the iterative coupling steps and/or to close gaps in the accessible compound space, enabling straightforward access also to iodinated compounds

Herein, the first Oxone-mediated direct arylhydroxylation of activated alkenes were developed for the synthesis of valuable hydroxyl-containing oxindoles and 3,4-dihydroquinolin-2-ones. The products were controlled by adjusting the structure of the initial alkenes. Moreover, the reaction were performed under simple conditions without any external additives or catalysts. Primary mechanistic studies showed that this reaction were a tandem process involving epoxidation and subsequent Friedel-Crafts alkylation, and oxone played a dual role (both the oxidant and proton source) in this process.

Zhang, Mingjun published the artcileGeneration and precise control of sulfonyl radicals: visible-light-activated redox-neutral formation of sulfonates and sulfonamides, Synthetic Route of 5961-59-1, the main research area is arylmethacrylamide dimethylsulfamoyl chloride iridium catalyst photochem sulfonation radical cyclization; sodium dimethyl oxoindolinyl methanesulfonate preparation; alkylsulfamoyl chloride arylmethacrylamide iridium catalyst photochem sulfonation radical cyclization; oxoindolinyl methanesulfonamide preparation.

A protocol for the generation and precise control of the sulfonyl radical from dimethylsulfamoyl chloride was reported. Different kinds of alkyl sulfonates and sulfonamides were efficiently and selectively obtained under redox-neutral conditions by controlling the reactivity of photocatalysts. A mechanism for the generation of sulfamoyl and sulfonate radicals from dimethylsulfamoyl chloride and the followed sulfonation and sulfonamidation were proposed. This reaction system offers a distinct advantage over traditional oxidation or reduction sulfonation methods in not requiring the use of sulfur dioxide, sulfonic acid, a stoichiometric reductant, or a stoichiometric oxidant. Thus, it should be of practical value for the late-stage functionalization of natural products or medicines.

B-homologation reactions represent an efficient and programmable approach to prepare alkylboronates, which are valuable and versatile synthetic intermediates. The typical B-homologation reaction, also known as the Matteson reaction, involves formal carbenoid insertions into C-B bonds. Here the authors report the development of aza-Matteson reactions via carbenoid insertions into the N-B bonds of aminoboranes. By changing the leaving groups of the carbenoids and altering Lewis acid activators, selective mono- and double-methylene insertions can be realized to access various α- and β-B-substituted tertiary amines, resp., from common secondary amines. The derivatization of complex amine-containing bioactive mols., diverse functionalization of the boronate products, and sequential insertions of different carbenoids also were achieved.

Wexler, Ryan P. published the artcileElectrochemically Enabled Chan-Lam Couplings of Aryl Boronic Acids and Anilines, COA of Formula: C8H11NO, the main research area is aryl amine preparation; aniline aryl boronic acid Chan Lam coupling reaction.

The Chan-Lam reaction remains a highly utilized transformation for C-N bond formation. However, anilines remain problematic substrates due to their lower nucleophilicity. To address this problem, we developed an electrochem. mediated Chan-Lam coupling of aryl boronic acids and amines utilizing a dual copper anode/cathode system. The mild conditions identified have enabled the preparation of a wide range of functionalized biarylanilines in good yields and chemoselectivities.
