Bains, Amreen K. published the artcileBorrowing Hydrogen-Mediated N-Alkylation Reactions by a Well-Defined Homogeneous Nickel Catalyst, HPLC of Formula: 1885-29-6, the main research area is borrowing hydrogen mediated nitrogen alkylation aniline alc; well defined homogeneous nickel catalyzed alkylation redox active ligand.

We report herein a well-defined and bench-stable azo-phenolate ligand-coordinated nickel catalyst which can efficiently execute N-alkylation of a variety of anilines by alc. We demonstrate that the redox-active azo ligand can store hydrogen generated during alc. oxidation and redelivers the same to an in-situ-generated imine bond to result in N-alkylation of amines. The reaction has wide scope, and a large array of alcs. can directly couple to a variety of anilines. Mechanistic studies including deuterium labeling to the substrate establishes the borrowing hydrogen method from alcs. and pinpoints the crucial role of the redox-active azo moiety present on the ligand backbone. Isolation of the ketyl intermediate in its trapped form with a radical quencher and higher kH/kD for the alc. oxidation step suggest altogether a hydrogen-atom transfer (HAT) to the reduced azo backbone to pave alc. oxidation as opposed to the conventional metal-ligand bifunctional mechanism. This example clearly demonstrates that an inexpensive base metal catalyst can accomplish an important coupling reaction with the help of a redox-active ligand backbone.

Zhang, Xinyu published the artcileUse of trifluoroacetaldehyde N-tfsylhydrazone as a trifluorodiazoethane surrogate and its synthetic applications, Formula: C7H6N2, the main research area is thiol trifluorodiazoethane iron porphyrin catalyst difluoroalkenylation; alc trifluorodiazoethane iron porphyrin catalyst difluoroalkenylation; amine trifluorodiazoethane iron porphyrin catalyst difluoroalkenylation; unsaturated compound trifluorodiazoethane iron porphyrin catalyst Doyle Kirmse reaction; alkene trifluorodiazoethane iron porphyrin catalyst diastereoselective cyclopropanation.

The development of trifluoroacetaldehyde N-tfsylhydrazone (TFHZ-Tfs) as a CF3CHN2 surrogate, which was capable of generating CF3CHN2 in-situ under basic conditions was reported. The reaction conditions employed in this chem. enabled a difluoroalkenylation of X-H bonds (X = N, O, S, Se), affording a wide range of heteroatom-substituted gem-difluoroalkenes, along with Doyle-Kirmse rearrangements and trifluoromethylcyclopropanation reactions, with superior outcomes to approaches using pre-formed CF3CHN2. Given the importance of generally applicable fluorination methodologies, the use of TFHZ-Tfs thus creates opportunities across organic and medicinal chem., by enabling the wider exploration of the reactivity of trifluorodiazoethane.

Nasibipour, Mina published the artcileTuning of the redox potential and catalytic activity of a new Cu(II) complex by o-iminobenzosemiquinone as an electron-reservoir ligand, Application of 2-Aminobenzonitrile(Flakes or Chunks), the main research area is preparation crystal mol structure copper iminobenzosemiquinone complex; EPR spectra magnetic property copper iminobenzosemiquinone complex; cyclic voltammetry copper iminobenzosemiquinone complex; alc oxidation catalyst copper iminobenzosemiquinone complex; homocoupling catalyst copper iminobenzosemiquinone complex.

The synthesis and characterization of a new Cu(II) complex, LNIS2CuII (LNIS = o-iminobenzosemiquinone), are reported. X-ray crystallog. studies showed that two o-iminobenzosemiquinone radicals form a distorted square-planar geometry around the Cu(II) center of LNIS2CuII. Magnetic measurements revealed the paramagnetic character of the complex caused by the presence of three unpaired electrons located on the o-iminobenzosemiquinonate ligands and the CuII center. Magnetochem. experiments, and EPR and DFT studies prove that the ground state of the complex is a doublet, which is consistent with the ferromagnetic coupling between Cu(II) and o-iminobenzosemiquinone centers and stronger antiferromagnetic coupling between the iminobenzosemiquinone moieties. The ligand-centered redox reactions of the complex were studied by cyclic voltammetry. Aerobic oxidation of alcs. to aldehydes with TEMPO was studied in the presence of LNIS2CuII. Furthermore, LNIS2CuII is an efficient catalyst in homo-coupling of terminal alkynes.

Qian, Deyun published the artcileChiral Alkyl Amine Synthesis via Catalytic Enantioselective Hydroalkylation of Enecarbamates, Product Details of C6H4N2, the main research area is aryl oxazoline preparation; enecarbamates alkyl halide nickel oxazoline catalyst enantioselective hydroalkylation; alkyl amine preparation.

A nickel-catalyzed hydroalkylation method to assemble a wide range of chiral alkyl amines from enecarbamates (N-Cbz-protected enamines) and alkyl halides with high regio- and enantioselectivity was reported. The method works for both nonactivated and activated alkyl halides and was able to produce enantiomerically enriched amines with two minimally differentiated α-alkyl substituents. The mild conditions led to high functional group tolerance, which is demonstrated in the postproduct functionalization of many natural products and drug mols., as well as the synthesis of chiral building blocks and key intermediates to bioactive compounds

Chand, Pooran published the artcileDesign and Synthesis of Benzoic Acid Derivatives as Influenza Neuraminidase Inhibitors Using Structure-Based Drug Design, Safety of Methyl 3-amino-5-cyanobenzoate, the main research area is benzoic acid derivative preparation neuraminidase inhibitor; structure activity benzoic acid neuraminidase inhibitor; crystal structure benzoic acid neuraminidase complex; influenza neuraminidase inhibitor benzoic acid preparation.

A series of 94 benzoic acid derivatives were synthesized and tested for their ability to inhibit influenza neuraminidase. The enzyme-inhibitor complex structure was determined by x-ray crystallog. anal. for compounds which inhibited the enzyme. The most potent compound tested in vitro, (4-(acetylamino)-3-guanidinobenzoic acid) (I), had an IC50 = 2.5 × 10-6 M against N9 neuraminidase. Compound I was oriented in the active site of the neuraminidase in a manner that was not predicted from the reported active site binding of GANA (II) with neuraminidase. In a mouse model of influenza, I did not protect the mice from weight loss due to the influenza virus when dosed intranasally.

We present a novel probe design for ambient laser-based mass spectrometry imaging combining electrospray ionization (ESI) and atm. pressure chem. ionization (APCI) in a single probe, compatible with a com. laser ablation electrospray ionization (LAESI) instrument. Here we describe the probe design considerations and features, as well as an inhouse developed data processing routine designed to extract accurate mass spectrometry imaging data from ambient laser ablation post-ionization experiments We characterize the probe performance in both APCI and ESI mode on a selection of compounds and show improved pixel-to-pixel repeatability for LA-APCI as compared to LAESI. We apply the dual ionization probe in APCI mode in a time series experiment to monitor agrochems. on tomato plants. We investigate the translocation of fungicide isotianil and one of its metabolites, anthranilonitrile, by mass spectrometry imaging over a period of two weeks after application on a leaf surface. LA-APCI-MSI shows translocation of anthranilonitrile from treated leaves towards non-treated leaves. In summary, we demonstrate that LA-APCI imaging is a valuable addition to the ambient mass spectrometry toolbox, with particular advantages for imaging experiments across a variety of compounds
