Nguyen, Vu T. published the artcileVisible-Light-Enabled Direct Decarboxylative N-Alkylation, SDS of cas: 1885-29-6, the main research area is visible light decarboxylative alkylation aromatic carbocyclic acid heterocycle amine; acridine catalyst; amination; carboxylic acids; copper catalysis; photocatalysis; visible light.

The development of efficient and selective C-N bond-forming reactions from abundant feedstock chems. remains a central theme in organic chem. owing to the key roles of amines in synthesis, drug discovery, and materials science. Herein, the authors present a dual catalytic system for the N-alkylation of diverse aromatic carbocyclic and heterocyclic amines directly with carboxylic acids, by-passing their preactivation as redox-active esters. The reaction, which is enabled by visible-light-driven, acridine-catalyzed decarboxylation, provides access to N-alkylated secondary and tertiary anilines and N-heterocycles. Addnl. examples, including double alkylation, the installation of metabolically robust deuterated Me groups, and tandem ring formation, further demonstrate the potential of the direct decarboxylative alkylation (DDA) reaction.

An efficient and sustainable synthetic protocol has been presented to synthesis and 5-substituted 1H-tetrazole privileged heterocyclic substructures I (R = Ph, 4-formylphenyl, pyridin-2-yl, etc.). The synthetic protocol involves two-component reaction between aryl nitriles RCN and NaN3 in water using complex of L-lysine-palladium nanoparticles (NPs) modified Fe3O4 nanoparticles as magnetically separable, recyclable, and reusable heterogeneous catalyst. Magnetically retrievable L-lysine-Pd(0) modified Fe3O4 nanoparticles were applied in [2+3] cycloaddition synthesis of 5-substituted 1H-tetrazoles I. The advantages of this strategy include easy recovery and efficient reusability of the expensive Pd NPs, obtaining high yields of [2+3] cycloaddition and short reaction times, and all of the reported synthetic strategies are being performed in water as green solvent for a wide range of substrates.

Nagasaki, Yo-hei published the artcileDehydration of Amides to Nitriles over Heterogeneous Silica-Supported Molybdenum Oxide Catalyst, Application of Picolinonitrile, the main research area is silica support molybdenum oxide catalyst preparation surface area; amide silica support molybdenum oxide catalyst dehydration; nitrile preparation.

Silica-supported molybdenum oxide (MoOx/SiO2) with 4.8 wt% Mo (0.5 mmol g-1) was an effective and reusable heterogeneous catalyst for dehydration of 2-furamide to 2-furonitrile (96% yield). The catalyst was applicable to the dehydration of various amides including heteroaromatic, aromatic and alkyl amides, providing the corresponding nitriles in high yields (87-97%). Based on the results of catalyst characterizations (XRD, TEM, UV-vis, Raman) and activity tests, MoOx species are highly dispersed over SiO2, and heptamolybdate anion ([Mo7O24]6-) and isolated dioxo ((O=)2MoO2) were mainly formed on the SiO2 support of the optimal MoOx/SiO2 catalyst. The strong Bronsted acid sites (Mo-OH-Si site) can be formed from the MoOx species and the adjacent silanol group, and the acid-base pair site (Mo(=O)OHSi site) of the strong Bronsted acid site (MoOH-Sisite) and base site (Mo=O) over MoOx/SiO2 catalyst could be themain active site for the dehydration of amides.

Chen, Rui-Jia published the artcileDiamides conformationally restricted with central amino acid: Design, synthesis, and biological activities, Category: nitriles-buliding-blocks, the main research area is diamide amino acid preparation insecticidal structure activity relationship.

Diamide insecticides, represented by chlorantraniliprole (CHL), were widely applied in the control of lepidopteran insects. In efforts to develop bioactive diamides with novel scaffolds, author design and synthesized a series of diamides containing central amino acids I (R1 = R2 = H, Me, t-Bu; -R1R2- = -(CH2)2-, -(CH2)3-, -(CH2)4-, etc.; R3 = i-Pr, Bn, 2-ClC6H4, etc.) to conformationally simulate CHL. Bioassay results indicated that most compounds containing 1-aminocyclopropane-1-carboxylic acid exhibited excellent larvacidal potency against Mythimna sep. and Plutella xylostella. After a systematic structure-activity relationship study, I (-R1R2- = -(CH2)2-; R3 = 3-NCC6H4) was identified as a potential insecticidal candidate with LC50 values of 34.920 mg·L-1 against M. sep. and 61.992 mg·L-1 on P. xylostella. Finally, mol. docking revealed the possible binding mode of I (-R1R2- = -(CH2)2-; R3 = 3-NCC6H4) with the target protein, ryanodine receptors.

Begam, Hasina Mamataj published the artcileA directing group switch in copper-catalyzed electrophilic C-H amination/migratory annulation cascade: divergent access to benzimidazolone/benzimidazole, Safety of Picolinonitrile, the main research area is benzimidazole benzimidazolone preparation directing group switch; protected naphthylamine benzoyloxyamine copper catalyst electrophilic amination migratory annulation.

Authors present here a copper-catalyzed electrophilic ortho C-H amination of protected naphthylamines with N-(benzoyloxy)amines, cyclization with the pendant amide, and carbon to nitrogen 1,2-directing group migration cascade to access N,N-disubstituted 2-benzimidazolinones. Remarkably, this highly atom-economic tandem reaction proceeds through a C-H and C-C bond cleavage and three new C-N bond formations in a single operation. Intriguingly, the reaction cascade was altered by the subtle tuning of the directing group from picolinamide to thiopicolinamide furnishing 2-heteroaryl-imidazoles via the extrusion of hydrogen sulfide. This strategy provided a series of benzimidazolones and benzimidazoles in moderate to high yields with low catalyst loading (66 substrates with yields up to 99%). From the control experiments, it was observed that after the C-H amination an incipient tetrahedral oxyanion or thiolate intermediate is formed via an intramol. attack of the primary amine to the amide/thioamide carbonyl. It undergoes either a 1,2-pyridyl shift with the retention of the carbonyl moiety or H2S elimination for scaffold diversification. Remarkably, inspite of a pos. influence of copper in the reaction outcome, from authors preliminary investigations, the benzimidazolone product was obtained in good to moderate yields in two steps under metal-free conditions. The N-pyridyl moiety of the benzimidazolone was removed for further manipulation of the free NH group.
