Gram-Scale Synthesis of the (-)-Sparteine Surrogate and (-)-Sparteine

An 8-step, gram-scale synthesis of the (-)-sparteine surrogate (22% yield, with just 3 chromatographic purifications) and a 10-step, gram-scale synthesis of (-)-sparteine (31% yield) are reported. Both syntheses proceed with complete diastereocontrol and allow access to either antipode.

3D Nitrogen and Sulfur Co -Doped Graphene/Integrated Polysaccharides for Electrochemical Recognition Tryptophan Enantiomers

Polysaccharides based on carboxymethyl beta-cyclodextrin (beta-CD-COOH) and chitosan (CS) were synthesized by amidation reaction between-COOH on beta-CD-COOH and -NH2 on CS to develop the electrochemical sensors. The sensor was constructed by combining the advantages of the polysaccharide CS -beta-CD and the guest molecule and the 3D N, S co-doped graphene (NSG). CS-beta-CD was used as chiral selector can provide a large number of chiral sites and NSG served as base material can improve electrochemical signal. The enantioselectivity of the chiral platform for tryptophan (Trp) enantiomers was studied by differential pulse voltammetry (DPV). NSG/CS-beta-CD modified GCE showed higher electrochemical signal for L-Trp than D-Trp. When forming diastereoisomeric enantiomer-selector complexes between Trp isomers and NSG/CS-beta-CD, there showed different steric hindrances, which made it easier for L-Trp to penetrate the modified electrode film to reach the electrode surface, thus producing a larger peak current. UV-vis further proved that CS-beta-CD has higher binding energy to D-Trp. In addition, the proposed electrochemical sensor can be used to detect actual samples. Therefore, the proposed electrochemical chiral interface can be used as a promising chiral sensing platform for enantiomer recognition of chiral compounds. (C) 2019 The Electrochemical Society.

Manipulation of Valley Pseudospin by Selective Spin Injection in Chiral Two-Dimensional Perovskite/Monolayer Transition Metal Dichalcogenide Heterostructures

Monolayer two-dimensional (2D) transition metal dichalcogenides (TMDs) have attracted great interest in spintronics and valleytronics due to the spin-valley locking effect. To efficiently control and manipulate the valley pseudospin is of paramount importance for valley-based electronics and optoelectronics. A variety of strategies have been developed to address the valley pseudospin including optical, electrical, and magnetic methods; nonetheless, they involve either below liquid-nitrogen temperature or an external magnetic field, which increases the cost and complexity of the devices. Here, we report a straightforward way to manipulate valley polarization in monolayer TMDs via selective spin injection in chiral 2D perovskite/monolayer TMD (e.g., MoS2 and WSe2) van der Waals heterostructures without requiring an external magnetic field or specially designed device structures. We show the dangling-bond-free vdW interface can allow an impressive average spin injection efficiency of 78% to produce persistent valley polarization in monolayer MoS2 (WSe2) over 10% from liquid-nitrogen temperature to above 200 K. We attribute the valley polarization of monolayer MoS2 (WSe2) to selective spin injection from chiral 2D perovskites, which can effectively introduce population imbalance between valleys in monolayer MoS2 (WSe2). Our findings provide an alternative strategy to manipulate the valley polarization in TMDs without requiring circularly polarized light excitation, below liquid-nitrogen temperature, or external magnetic field, and thus would promote the development of perovskite-based spintronic and valleytronic devices.

Chromatographic approach to study the configurational stability of Ni(II) complexes of amino-acid Schiff bases possessing stereogenic nitrogen

Herein, we disclose the design of a model Ni(II) complex of glycine Schiff base possessing single-nitrogen stereogenic center, which was successfully used for high-performance liquid chromatography (HPLC)-assisted assessment of its configurational stability. The major finding is that the configurational stability of the Ni(II)-coordinated nitrogen is profoundly dependent on the reaction conditions used, in particular the solvent, and can range from inconsequential (t(1/2) less than 5 min) to virtually completely stable (t(1/2) 90 y). The discovery reported in this study most likely to be of certain theoretical and synthetic value.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 96-47-9, you can contact me at any time and look forward to more communication. SDS of cas: 96-47-9.

Asymmetric sequential annulation/aldol process of 4-isothiocyanato pyrazolones and allenones: access to novel spiro[pyrrole-pyrazolones] and spiro[thiopyranopyrrole-pyrazolones]

A catalytic asymmetric sequential annulation/aldol reaction of 4-isothiocyanato pyrazolones and allenyl ketones has been developed, which furnished a series of spiro[pyrrole-pyrazolone] heterocycles and structurally novel spiro[thiopyranopyrrole-pyrazolone] derivatives in good yields with high to excellent enantioselectivities. Notably, parallel resolution of racemic spiro[pyrrole-pyrazolones] was achieved by a catalyst-controlled asymmetric intramolecular vinylogous aldol process.

Research Progress in Asymmetric Reactions of Imines Using Chiral Primary Amines as Organocatalysts

Chiral primary amine is a kind of important small organic molecule catalyst in the field of asymmetric organocatalysis. Like secondary amine catalyst, primary amine can react with carbonyl compounds to form reactive intermediate of enamine or iminium to catalyze various asymmetric reactions, achieving excellent enantioselectivities. The catalytic asymmetric 1,2-addition to the electrophilic C=N double bond of imines (involving imine intermediates in the reaction process) is the most efficient way to obtain nitrogen-containing compounds bearing alpha-chiral center. In recent years, the highly enantioselective asymmetric reaction of imines by chiral primary amine catalysts has made some progress, so this topic is summarized and prospected.

Conversion of anilines to chiral benzylic amines via formal one-carbon insertion into aromatic C-N bonds

Insertion of atoms into aromatic carbon-nitrogen bonds is an appealing method for the synthesis of nitrogen-containing molecules and it has the advantage of the availability and abundance of anilines. However, the direct cleavage of aromatic carbon-nitrogen bonds is challenging due to the particularly inert and stable nature of these bonds. Here we report a formal, enantioselective one-carbon insertion into an aromatic carbon-nitrogen bond via an aromaticity dissembly-reconstruction process to directly convert anilines to chiral alpha -branched benzylic amines. The process involves oxidative dearomatization of para-substituted anilines, chiral sulfur ylide-mediated asymmetric aziridination, and subsequent rearrangement. Chiral sulfur ylides serve as one-carbon insertion units. Atom insertion into aromatic carbon-nitrogen (C-N) bonds is useful for the synthesis of nitrogen-containing molecules, but challenging due to the inert nature of these bonds. Here, the authors report one-carbon insertion into aromatic C-N bonds to directly convert anilines to chiral benzylic amines.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 96-47-9 is helpful to your research. Computed Properties of C5H10O.

Desymmetrization of meso-Dicarbonatecyclohexene with beta-Hydrazino Carboxylic Esters via a Pd-Catalyzed Allylic Substitution Cascade

The desymmetrization of meso-dicarbonatecyclohexene with beta-hydrazino carboxylic esters has been achieved via a RuPHOX/Pd-catalyzed allylic substitution cascade for the construction of chiral hexahydrocinnoline derivatives with high performance. Mechanistic studies reveal that the reaction exploits a pathway different from that of our previous work and that the first nitrogen nucleophilic process is the rate-determining step. The protocol could be conducted on a gram scale without any loss of catalytic behavior, and the corresponding chiral hexahydrocinnolines can undergo diverse transformations.
