Zheng, Dan published the artcileAbsolute control of helicity at the C-termini in quinoline oligoamide foldamers by chiral oxazolylaniline moieties, Recommanded Product: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is helicity induction quinoline oligoamide foldamer chiral oxazolylaniline.

Absolute one-handed chiral quinoline tetramers and octamers containing different oxazolylanilines at the C-terminus have been synthesized (e.g., I). The absolute one-handed sense and diastereomeric excess values were valued by 1NMR. X-ray crystal diffraction and CD studies reveal that the S-oxazolylaniline always induces a P-handed helicity and the absolute helicity is driven by the stable three-center hydrogen bonding between protons in the amide and N atoms in oxazolylaniline and adjacent quinoline ring. CPL investigations demonstrated that S-CQn-a∼d are CPL active and its glum values are dependent on its length. Interestingly, the sizes of the substituents in the chiral centers are different, however, they exert no effect on the dissym. factors gabs and glum of quinoline oligoamide foldamers.

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.

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.

Wang, Zhichao published the artcilePreparation and photophysical properties of quinazoline-based fluorophores, Synthetic Route of 1885-29-6, the main research area is photophys property quinazoline based fluorophore preparation.

The donor-acceptor design is a classic method of synthesizing new fluorescent mols. In this study, a series of new fluorescent compounds (1-10) were synthesized based on 2-(3,5-bis(trifluoromethyl)phenyl)-quinazoline acceptor and various amino donors. The fluorescent emissions of 1-10 cover the spectrum from 414 nm to 597 nm in cyclohexane solutions with various amino donors on 4- or 7-positions of quinazoline. Ultimately, compounds 1 and 2 presented the highest photoluminescence quantum yield (QY) over 80%, while compound 10 provided the largest Stokes shift (161 nm) in cyclohexane. Most of them have strong emissions in aggregated states such as in nanoparticles, in powders, in crystals and in films. Mechanochromic properties were observed for compounds 1, 2, 4 and 7. Furthermore, blue OLEDs were fabricated by using compound 2 or 7 as the active layer.

Walker, Benjamin R. published the artcileMediator-Enabled Electrocatalysis with Ligandless Copper for Anaerobic Chan-Lam Coupling Reactions, Product Details of C7H6N2, the main research area is mediator electrocatalysis copper anaerobic Chan Lam coupling reaction.

Simple Cu salts serve as catalysts to effect C-X bond-forming reactions in some of the most used transformations in synthesis, including the oxidative coupling of aryl boronic acids and amines. However, these Chan-Lam coupling reactions have historically relied on chem. oxidants that limit their applicability beyond small-scale synthesis. Despite the success of replacing strong chem. oxidants with electrochem. for a variety of metal-catalyzed processes, electrooxidative reactions with ligandless Cu catalysts are plagued by slow electron-transfer kinetics, irreversible Cu plating, and competitive substrate oxidation Herein, the authors report the implementation of substoichiometric quantities of redox mediators to address limitations to Cu-catalyzed electrosynthesis. Mechanistic studies reveal that mediators serve multiple roles by (i) rapidly oxidizing low-valent Cu intermediates, (ii) stripping Cu metal from the cathode to regenerate the catalyst and reveal the active Pt surface for proton reduction, and (iii) providing anodic overcharge protection to prevent substrate oxidation This strategy is applied to Chan-Lam coupling of aryl-, heteroaryl-, and alkylamines with arylboronic acids in the absence of chem. oxidants. Couplings under these electrochem. conditions occur with higher yields and shorter reaction times than conventional reactions in air and provide complementary substrate reactivity.

Mannisto, Jere K. published the artcileOne-Step Synthesis of 3,4-Disubstituted 2-Oxazolidinones by Base-Catalyzed CO2 Fixation and Aza-Michael Addition, Application of 2-Aminobenzonitrile(Flakes or Chunks), the main research area is amine alkenylbromide carbon dioxide tetramethylguanidine carboxylation aza Michael addition; oxazolidinone preparation regioselective; Michael addition; carbon dioxide fixation; cyclization; heterocycles; organocatalysis.

A new, single-step approach to 3,4-disubstituted 2-oxazolidinones by aza-Michael addition using CO2 as a carbonyl source and 1,1,3,3-tetramethylguanidine (TMG) as a catalyst was reported. The modular reaction, which occurred between a γ-brominated Michael acceptor, CO2 and an arylamine, aliphatic amine or phenylhydrazine was performed under mild conditions. The regiospecific reaction displayed good yields (average 75 %) and excellent functional-group compatibility. In addition, late-stage functionalization of drug and drug-like mols. wais demonstrated. The exptl. results suggested a mechanism consisting of several elementary steps: TMG-assisted carboxylation of aniline; generation of an O-alkyl carbamate; and the final ring-forming step through an intramol. aza-Michael addition

Nie, Xufeng published the artcileAcceptorless dehydrogenation of amines to nitriles catalyzed by N-heterocyclic carbene-nitrogen-phosphine chelated bimetallic ruthenium (II) complex, Category: nitriles-buliding-blocks, the main research area is heterocyclic carbene nitrogen phosphine chelate bimetallic ruthenium complex preparation; amine ruthenium complex catalyst dehydrogenation green chem; nitrile preparation.

A clean, atom-economical and environmentally friendly route for acceptorless dehydrogenation of amines to nitriles by combining a new dual N-heterocyclic carbene-nitrogen-phosphine ligand R(CNP)2 (R = o-xylyl) with a ruthenium precursor [RuCl2(η6-C6H6)]2 was developed. In this system, the electronic and steric factors of amines had a negligible influence on the reaction and a broad range of functional groups were well tolerated. All of the investigated amines was converted to nitriles in good yield of up to 99% with excellent selectivity. The unprecedented catalytic performance of this system was attributed to the synergistic effect of two ruthenium centers chelated by R(CNP)2 and a plausible reaction mechanism was proposed according to the active species found via in-situ NMR and HRMS.
