Zhao, Xin published the artcileCu-Catalyzed Intermolecular γ-Site C-H Amination of Cyclohexenone Derivatives: The Benefit of Bifunctional Ligands, Synthetic Route of 5961-59-1, the main research area is aniline cyclohexenone copper catalyst regioselective amination green chem; amino alc preparation antibacterial antioxidant; cyclohexadienyl oxy silyl ether aniline copper regioselective diastereoselective amination; aminocyclohexenone preparation green chem.

Utilizing 1,10-phenanthroline-type bifunctional ligands, an efficient Cu-catalyzed intermol. site-selective remote C-H amination using cyclohexenone derivatives and anilines was realized. The amide group installed on the bifunctional ligand played a key role in stabilizing the N-centered radical generated in-situ to realize C-N-directed formation. Meanwhile, a useful catalytic system for site-selective intermol. remote γ-C-H amination to p-aminophenols and γ-aminated enones was established. This economical and practical approach using oxygen as the terminal oxidant was mild and environmentally friendly.

Warsitz, Michael published the artcileTwo-Step Procedure for the Synthesis of 1,2,3,4-Tetrahydro-quinolines, Application In Synthesis of 5961-59-1, the main research area is chlorostyrene aniline alkyl titanium regioselective hydroaminoalkylation catalyst; amine aryl alkyl preparation palladium Buchwald Hartwig amination; tetrahydroquinoline preparation.

A new two-step procedure that includes an initial regioselective intermol. hydroaminoalkylation of ortho-chlorostyrenes with N-methylanilines and a subsequent intramol. Buchwald-Hartwig amination gives direct access to 1,2,3,4-tetrahydroquinolines. The hydroaminoalkylation reaction of the ortho-chlorostyrenes is catalyzed by a 2,6-bis(phenylamino)pyridinato titanium complex which delivers the linear regioisomers with high selectivities. In addition, the formation of unexpected dihydroaminoalkylation products from styrenes and N-methylanilines is reported.

Levinn, Carolyn M. published the artcileN-Methylation of Self-Immolative Thiocarbamates Provides Insights into the Mechanism of Carbonyl Sulfide Release, Quality Control of 5961-59-1, the main research area is self immolative methylated thiocarbamate carbonyl sulfide release mechanism.

Hydrogen sulfide (H2S) is an important biomol., and self-immolative thiocarbamates have shown great promise as triggerable H2S donors with suitable analogous control compounds; however, thiocarbamates with electron-deficient payloads are less efficient H2S donors. We report here the synthesis and study of a series of N-methylated esterase-triggered thiocarbamates that block the postulated unproductive deprotonation-based pathway for these compounds The relative reaction profiles for H2S release across a series of electron-rich and electron-poor N-Me aniline payloads are examined exptl. and computationally. We show that thiocarbamate N-methylation does block some side reactivity and increases the H2S release profiles for electron-poor donors. Addnl., we show that isothiocyanate release is not a competitive pathway, and rather that the reduced efficiency of electron-poor donors is likely due to other side reactions.

Zhao, Binlin published the artcileSingle-Electron-Transfer-Induced C(sp3)-N Couplings via C-C Bond Cleavage of Cycloketoxime Esters, Safety of 4-Methoxy-N-methylaniline, the main research area is copper photoredox catalyzed single electron transfer coupling cycloketoxime aniline.

A practical single-electron-transfer-induced selective C(sp3)-N coupling of cycloketoximes with anilines via C-C bond cleavage under copper-catalytic and synergetic photoredox/copper-catalytic reaction systems has been uncovered. These two powerful and simple protocols demonstrated excellent selectivity and good functional group compatibility without any base or ligand control. Preliminary mechanistic experiments indicated that a radical-mediated process was involved in these transformations.

Nguyen, Vu T. published the artcileVisible-Light-Enabled Direct Decarboxylative N-Alkylation, HPLC of Formula: 5961-59-1, 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 iron-catalyzed cross-dehydrogenative coupling [4 + 2] annulation of secondary/tertiary anilines with quinazolinones to generate quinoline-spiroquinzolinones I [R1 = H, 7-Me; R2 = n-Pr, 3-ClC6H4, Bn, etc.; R3 = H, 6-Br, 7-Me, etc.; X = O, S] was reported. The reaction proceeded smoothly with a relatively broad variety of functional groups, a cheap transition metal catalyst (FeCl3), and environmentally friendly oxidant (H2O2/O2) under mild reaction conditions. Creatively, N-methylanilines were employed for the first time for the cycloaddition as both Me and methylene sources attached to the N atom of tetrahydroquinolines.

Takaishi, Kazuto published the artcileUnexpected Macrocyclic Multinuclear Zinc and Nickel Complexes that Function as Multitasking Catalysts for CO2 Fixations, Safety of 4-Methoxy-N-methylaniline, the main research area is epoxide carbon dioxide fixation binaphthyl bipyridyl zinc nickel catalyst; cyclic carbonate preparation; amine hydrosilane zinc nickel catalyst formylation methylation chemoselective DFT; tertiary amine preparation; N-functionalization; carbon dioxide fixation; cyclic carbonates; multinuclear complexes; self-assembly.

Unique self-assembled macrocyclic multinuclear ZnII and NiII complexes with binaphthyl-bipyridyl ligands (L) were synthesized. X-ray anal. revealed that these complexes consisted of an outer ring (Zn3L3 or Ni3L3) and an inner core (Zn2 or Ni). In the ZnII complex, the inner Zn2 part rotated rapidly inside the outer ring in solution on an NMR timescale. These complexes exhibited dual catalytic activities for CO2 fixations: synthesis of cyclic carbonates from epoxides and CO2 and temperature-switched N-formylation/N-methylation of amines with CO2 and hydrosilane.
