Electrochemical water splitting is considered as a promising approach to storing renewable electricity in the form of hydrogen fuel. In this work, we report the design and electrocatalytic properties of chiral CuO@Ni with three dimensional (3D) continuous macroporous framework. With the chiral CuO@Ni as anode, the OER overpotential required to achieve the current density of 10 mA/cm(2) was as low as 110 mV in 0.1 M KOH electrolyte, and the hydrogen production rate of water splitting reaction could reach 1070 nL/s. Moreover, the OER overpotential could be regulated easily by controlling the deposition time of chiral CuO layer on Ni. The high catalytic activity of chiral CuO@Ni for water splitting is closely associated with the Chiral-induced spin selectivity (CISS) effect, the large reactive area provided by its 3D macroporous structure, and the effective cooperation between chiral CuO and Ni foam that facilitated the transportation of spin aligned electrons from chiral CuO layer to Ni. The results shown in this work indicate a simple and promising strategy to improve the electrocatalytic activity of other chiral earth-abundant catalysts for water splitting.

An efficient asymmetric hydroesterfication of diarylmethyl carbinols is developed for the first time with a Pd-WingPhos catalyst, resulting in a series of chiral 4-aryl-3,4-dihydrocoumarins in excellent enantioselectivities and good yields. The method features mild reaction conditions, a broad substrate scope, use of easily accessible starting materials, and low palladium loadings. A plausible stereochemical model is also proposed with the Pd-WingPhos catalyst. This method has enabled a 4-step asymmetric synthesis of (R)-tolterodine from readily available starting materials.

Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 7512-17-6, Name is N-Acetyl-D-glucosamine, molecular formula is , belongs to chiral-catalyst compound. In a document, author is Stegner, Philipp C., Computed Properties of C8H15NO6.

Hybrid catalysts consisting of alkaline earth iodides (AeI(2)) and the Schwesinger base(tBu)P4 catalyse the intramolecular alkene hydroamination of H2C=CHCH2CR2CH2NH2[CR2=CPh2, C(CH2)(5), CMe2]. Activities decrease along the row: Ca > Sr >> Mg > Ba. Hybrid catalysts consisting of(tBu)P4 and ZnI2, AlI3, FeCI(3)or NaI were found to be fully inactive. Also, the hybrid catalyst(tBu)P3/CaI(2)was not active which means that the base strength of the non-nucleophilic organic base must be higher than that of(tBu)P3 (pK(a)BH(+)= 38.6). Combinations of(tBu)P4 with CaX2(X = Cl, Br, OiPr, OTf, NTf2) were found to be fully inactive which may in part be explained by poor solubility. The hybrid catalysis method is therefore limited to the combination(tBu)P4/CaI(2)but the iodide ligands may be partially or fully replaced by chiral ligands. Chiral modifications of the hybrid catalysts gave in intramolecular alkene hydroaminationeevalues up to 33 %.

The enantioselective synthesis of chiralN,N-acetals derived from alpha-dicarbonyl compounds has been achieved. Good yields and enantioselectivities were observed for the reaction with various alpha-dicarbonyl compounds with 2-aminobenzamides using chiral bis(imidazoline)-phosphoric acid catalysts. Based on these experimental investigations, a possible transition state is proposed to explain the origin of the asymmetric induction.

We report, herein, aminocatalytic coupling of alpha-substituted acrylaldehydes with alpha-diazoesters, leading to chemoselective C-H insertion or cyclopropanation depending on alpha-substituents of diazoesters. A chiral primary-secondary diamine catalyst derived from L-tert-leucine enabled the efficient promotion of both C-H insertion and cyclopropanation pathways in good yields and high enantioselectivities at room temperature without any metal or a Lewis acid cocatalyst. Mechanistic studies uncovered an iminium ion-mediated 1,3-dipolar cycloaddition pathway, wherein the electronic nature of diazocarbons dictates the chemoselectivity in this aminocatalytic cycle.

ZSM-5 zeolites are commonly used as a heterogeneous catalyst for reactions. Four ZSM-5 catalysts (with various crystallite sizes and a similar ratio of Si/Al) and their ball-milling/surface-poisoning derivates were used to convert L-lactic acid to L, L-lactide. The reaction products were analyzed by three independent analytical methods (i.e., Proton nuclear magnetic resonance (H-1 NMR), high-pressure liquid chromatography (HPLC), and chiral gas chromatography (GC)) for determining the L, L-lactide yield and L-lactic acid conversion. A clear size effect, i.e., smaller catalysts providing better performance, was observed. Further ball-milling/surface-poisoning experiments suggested that the size effect of the ZSM-5 catalysts originated from the diffusion-controlled nature of the reaction under the investigated conditions.

Azomethine ylides are useful intermediates for the rapid construction of chiral N-containing compounds. However, its synthetic potential has not been fully developed due to the limited reaction models. In combination with synergistic catalysis and azomethine ylide chemistry, we have developed several types of novel catalytic system including Cu/Pd, Cu/Ir and PTC/Ir catalysis, which can convert readily-available azomethine ylides to various high-valued molecules such as unnatural alpha-amino acids, homoallylic amines and N-heterocycles. Compared with the traditional mono-catalysis, the synergistic catalyst system exhibits enhanced catalytic efficiency and chiral induction ability in many cases. In addition, we have demonstrated that these strategies could be applied in the construction of bioactive compounds and natural products.

A chiral phosphoric acid-catalyzed asymmetric 1,4-addition of benzofuran-derived azadienes with 3-substituted indoles has been established, which offered enantioenriched tri(hetero)arylmethane products in generally good yields (up to 98 %) and high enantioselectivities (up to 99 : 1 er).

We herein report the well-defined two novel chiral palladium(II) complexes 1 (b-c), of the chiral N-fused tricyclic triazolooxazine derived mesoionic carbene (tz-MIC) ligand 1a . The chiral tricyclic PEPPSI type complex (pyridine enhanced pre-catalyst preparation stabilization and initiation) namely, trans-[tzMIC)-PdI2(pyridine)] (1b ), and the chiral tricyclic bis(tz-MIC)-palladium complex namely, cis-[tz-MIC)(2)PdCl2] (1c ). The chiral tricyclic trans-[tz-MIC)-PdI2(pyridine)] PEPPSI type complex (pyridine enhanced pre-catalyst preparation stabilization and initiation) (1b ) was directly obtained from their respective chiral tricyclic triazolooxazinium iodide salt (1a ), by treatment with PdCl2 and K2CO3 in pyridine in 77% yield. The chiral tricyclic triazolooxazinium iodide salt (1a ), was first converted to its in-situ silver analogue by reaction with Ag2O and then subsequently upon treatment with (COD)PdCl2 to produce the chiral tricyclic (tz-MIC)(2)PdCl2 type palladium complex (1c ) in 84% yield. All these palladium complexes were isolated for the first time and structurally characterized by (1) H NMR and C-13{H-1}-NMR spectroscopy, FT-IR spectroscopy, mass spectrometry, elemental analysis and single crystal X-ray crystallography.
