Organic carbonates, e.g., dimethyl carbonate and propylene carbonate were used as reaction media in enantioselective epoxidation of non-functionalized alkenes by using a series of chiral macrocyclic Mn(III) salen complexes (5 mol%) as catalyst with pyridine N-oxide as an axial base. This protocol worked effectively with urea hydrogen peroxide, as well as sodium hypochlorite as oxidants to give respective epoxides in high yields and ee (up to >91% in selected cases). Furthermore kinetic studies of the catalytic epoxidation reaction in dimethyl carbonate:methanol (optimized solvent mixture) with urea hydrogen peroxide as an oxidant showed first order dependence on catalyst and oxidant whereas it is zero order for the substrate, styrene.

The design, preparation, structural and spectroscopic analyses of topologically unique and enantiomerically pure alkyl phosphonamides are described. In the case of alpha-ethyl and alpha-benzyl phosphonamides, the geometry of both the secondary and tertiary carbanions was determined to be planar through deprotonation/deuteration/alkylation experiments. Stereoselective alkylations of such systems proceeded in good yields and with high diastereoselectivities. The resulting alpha,alpha-alkylated phosphonamides were hydrolyzed to give the corresponding alpha,alpha-alkyl phosphonic acids with high degrees of enantiomeric purity.

The unique structure of BINOL has been extensively used for enantioselective molecular recognition, which can be monitored by many detecting means, such as fluorescence, UVevis absorption, CD, electrochemistry, HPLC, NMR and X-ray crystallography. Various types of functional groups have been attached to the enantiomerically pure BINOL to build small molecules, dendrimers, oligomers, polymers, MOFs, HOFs and CSPs. These chiral materials not only differentiate two enantiomers of chiral substrates, but also have achieved rapid determination of ee, separation of racemic samples and chirality conversion for organic compounds including chiral amines, alcohols, carboxylic acids, ketones and sulfoxides. The research on the BINOL-based molecules has great potentials for many practical applications such as rapid chiral assay and chiral resolution. Thus, one would expect the continuous development of the BINOL chemistry in many research areas.

A series of new chiral mono- or bidentate phosphorus ligands were efficiently prepared through a key intermediate (S)-4-chloro-4,5-dihydro-3H-4-phosphacyclohepta[2,1-a;3,4-a?] binaphthalene and its derivatives. These ligands were applied in the Rh-catalyzed asymmetric hydrogenation of alpha-dehydro amino acids, enol acetates, itaconates, and enamides. Good to excellent enantioselectivities were obtained (up to 99.5% ee).

Porous crystalline materials, such as porous organic cages (POCs) and covalent organic frameworks (COFs), are important for a wide range of applications such as gas storage/separation, sensing and catalysis. A conventional synthetic approach for imine-based POCs and COFs usually involves the use of organic solvents/acid catalysts (such as AcOH or TFA). However, synthesizing and growing POC crystals and COF crystallites with enhanced crystallinity is not an easy-to-perform process, in which many reaction parameters need to be screened. To overcome these problems, we have proposed herein a facile and green synthetic strategy by adopting H2O/organic solvents/MOH (M = Na, K, and Cs) as reaction media to produce a series of phenol-based POCs and COFs. X-ray crystallography and molecular simulations have been used to confirm their structures in addition to NMR, mass and FT-IR spectra, and gas sorption experiments reveal their porosity and sorption properties. This new approach provides not only an efficient and alternative route to synthesize highly crystalline POCs and even COFs, but also insight into the crystallization process of these two kinds of porous materials, especially in the hydrous media.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.21436-03-3, Name is (1S,2S)-Cyclohexane-1,2-diamine, molecular formula is C6H14N2. In a Article，once mentioned of 21436-03-3, Computed Properties of C6H14N2

The asymmetric vinylogous Michael reaction of cyclohexenone/medium and large cyclic enones with 2-silyloxyfuran is still a synthetic challenge. In this report, we have explored 1,4-conjugate addition of an enantioselective chiral, primary diamine catalyzed, 2-silyloxy furan to various cyclic enones and beta-substituted cyclic enones. The reaction provided syn-Michael adducts (cycloalkane connected gamma-butenolide) with good yields, diastereo and enantioselectivities. Furthermore, the synthetic potential of these syn-Michael adducts is demonstrated by 1,4-addition of nucleophiles on the butenolide substructure.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C6H14N2, you can also check out more blogs about21436-03-3

Organic wide bandgap semiconductor is a hot research topic in optoelectronic fields. In this work, a series of diphenylether-, 9,9-biphenylfluorene- and tetraphenylsilane-centered wide bandgap materials are designed and synthesized. Comprehensive experiments and theoretical calculations are conducted to investigate their intrinsic thermal stability, photophysical property, electrochemical behavior and device performance, aiming at exploring the potentials of oxygen, sp3-hybridized carbon and silicon atoms for wide bandgap materials. They all can interrupt molecular conjugation to generate wide bandgaps. By modification of appropriate donor and acceptor, relatively high triplet energy level (ET) can be obtained in the resulting materials. Quantum chemical calculations indicate the sort of triplet energy levels of N-carbazole > fluorene > benzonitrile, which fully supports the experimental results. Tetraphenylsilane-based materials display lower LUMO levels than corresponding diphenylether- and 9,9-biphenylfluorene-centered materials owing to the dpi-ppi conjugation. Among them, DCzSiPy/FIrpic doped device gives the best device performance with maximum current efficiency of 35.6 cd/A and maximum external quantum efficiency of 16.8%, demonstrating the superiority of tetraphenylsilane skeleton. 9,9-Biphenylfluorene-based doped devices have comparable efficiencies with tetraphenylsilane-hosted ones, meaning 9,9-biphenylfluorene unit also can be a good constructing skeleton for wide bandgap host materials.

The structure-activity relationships of bisquinolines, a potentially important group of novel antimalarial drugs, were studied. The high-temperature (180-250C) synthesis of 4-aminoquinolines, including bisquinolines, by nucleophilic displacement was both fast and efficient. Several bisquinolines including (±)-trans-N1,N2-bis(7-trifluoroquinolin-4-yl) cyclohexane-1,2-diamine and 1R,2R-(-)-, 1S,2S-(+)-, (±)-trans- and cis-N1,N2-bis(7-chloroquinolin-4-yl)cyclohexane-1,2-diamine exhibited potent activity against Plasmodium berghei in mice; (+)-trans-N1,N2-bis(7-chloroquinolin-4-yl)cyclohexane-1,2-diamine was orally active. Our results indicate that these compounds conform to a putative receptor for quinoline antimalarials. In addition, a 7-haloquinoline linked by a heterocyclic bridge, at the 4-position, to another heterocycle (such as an acridine at the 9-position) maximally occupies the active site of our postulated target.
