I found the field of Chemistry very interesting. Saw the article Absolute asymmetric Strecker synthesis in a mixed aqueous medium: reliable access to enantioenriched alpha-aminonitrile published in 2019.0. Recommanded Product: Diphenylmethanamine, Reprint Addresses Kawasaki, T (corresponding author), Tokyo Univ Sci, Dept Appl Chem, Shinjyuku Ku, Tokyo 1628601, Japan.. The CAS is 91-00-9. Through research, I have a further understanding and discovery of Diphenylmethanamine

Without using chiral sources, the Strecker reaction of achiral hydrogen cyanide, p-tolualdehyde and benzhydrylamine gave enantioenriched L- or D-N-benzhydryl-alpha-( p-tolyl) glycine nitriles with up to > 99% ee in a mixed solvent of water and methanol. Therefore, total spontaneous resolution of alpha-aminonitriles could occur through a prebiotic mechanism of alpha-amino acid synthesis. Moreover, it was demonstrated that the repetition of partial dissolution and crystallization of a suspended conglomerate of aminonitrile under solution-phase racemization could generate the enantiomeric imbalance to afford, in combination with the amplification of chirality, an enantioenriched product in every case. Among the 73 experiments that were carried out, D-and L-enriched isomers occurred 36 and 37 times, respectively. This stochastic behavior, under achiral or racemic starting conditions, meets the requirements of the spontaneous absolute asymmetric Strecker synthesis. The implications of the present results for the origin of chirality of alpha-amino acids are discussed.

In this study, ABA triblock copolymers derived from 4,4′-(hexafluoroisopropylidene)-diphthalic anhydride-2,3,5,6-tetramethyl-1,4-phenylenediamine (6FDA-TeMPD; PI) and 3-hydroxy-1-adamantyl methacrylate (HAdMA) or 3,5-dihydroxy-1-adamantyl methacrylate (DHAdMA) have been synthesized via atom transfer radical polymerization to generate mechanically tough and thermally stable gas-separation membranes with composition-tunable transport properties. Due to the inherent thermodynamic incompatibility between the chemically dissimilar blocks, these two series of triblock copolymers appear microphase-separated. While the gas permeability coefficients of these triblock copolymer membranes are consistently lower than that of PI due to the reduced fractional free volume of HAdMA and DHAdMA, the solubility coefficients of the copolymers are higher than that of PI due presumably to specific interactions between the polar hydroxyl group(s) and penetrant gas molecules. These triblock copolymers synthesized from PI and hydrophilic adamantane derivatives constitute a new class of nanostructured polymeric materials possessing excellent thermomechanical properties in conjunction with designer gas-separation properties.

A novel easy-to-prepare magnetic catalyst, composed of palladium nanoparticles supported on surface-oxidized carbon-encapsulated iron nanoparticles, has been synthesized. The synthesis involved the reduction of palladium precursor in the presence of magnetic core-shell nanomaterial. The size of the palladium nanoparticles distributed over the support does not exceed 15 nm. The catalytic performance of this composite material was tested in hydrogenation of seven various nitro compounds to the respective amino derivatives. The composite exhibits excellent catalytic activity and can be easily separated from the reaction mixture after the reaction. The determined reaction yields were above 90 % and this value was not worsened even after ten cycles, for the case of hydrogenation of nitrobenzene. Importantly, the method is chromatography-free and employs the ammonium formate as a hydrogen source, which makes the herein presented protocol safer in comparison with the previously reported reductions in which highly dangerous gaseous hydrogen was used.

An improved five-step synthesis of triethylene glycol-substituted 4-(N-methyl-N-Boc-amino)styrylpyridine (6) is described. Using cost-effective starting materials, the developed synthesis route was synthetic, efficient, and chromatographic purification-free. The key point of the work is the one-pot synthesis of tert-butyl methyl(4-vinylphenyl)carbamate through methylation and elimination in the NaH/THF system. The new synthesis route shows the potential to achieve scaled-up preparation of 6 in the future.

Sickle Cell Anemia (SCA) is one of the most prevalent hereditary hematological diseases worldwide. The disease is characterized by chronic inflammation, hypercoagulable state, and pro-thrombotic profile, which lead the vaso-occlusive process. In this work, we described the antiplatelet activity and the ability to reduce tumor necrosis factor-alpha (TNF-) levels of phthalimide derivatives. All compounds inhibited platelet aggregation induced by collagen and adenosine diphosphate, at levels ranging from 26.0 to 74.2% and 30.7 to 79.6%, respectively. The compounds exhibited reduced bleeding time compared to acetylsalicylic acid (ASA). Moreover, compounds 4c and 10c inhibited TNF- levels at 73.5% and 65.0%, respectively. These findings suggest that phthalimide derivatives 4c and 10c are promising lead compounds useful to prevent vaso-occlusion and inflammation associated with the sickle cell anemia. [GRAPHICS] .

Nucleophilic substitutions of benzylic alcohols with sulfamides were achieved using an FeCl3 Lewis acid catalyst in MeNO2. It was necessary to adjust the reaction conditions to obtain efficient yields depending on the stability of the carbocation intermediates. The reaction could easily be performed, and it was revealed that a variety of diarylmethanols and benzylic alcohols were applicable to the reaction, irrespective of the type and position of the substituents. The sulfamide moieties were easily deprotected and converted into amine groups.

Enantioselective reduction of ketimines was demonstrated using chiral N-heterocyclic carbene (NHC)-stabilised borenium ions in frustrated Lewis pair catalysis. High levels of enantioselectivity were achieved for substrates featuring secondary N-alkyl substituents. Comparative reactivity and mechanistic studies identify key determinants required to achieve useful enantioselectivity and represent a step forward in the further development of enantioselective FLP methodologies.

We report on catalysis by a fuel-induced transient state of a synthetic molecular machine. A [ 2] rotaxane molecular shuttle containing secondary ammonium/amine and thiourea stations is converted between catalytically inactive and active states by pulses of a chemical fuel (trichloroacetic acid), which is itself decomposed by the machine and/or the presence of additional base. The ON-state of the rotaxane catalyzes the reduction of a nitrostyrene by transfer hydrogenation. By varying the amount of fuel added, the lifetime of the rotaxane ON-state can be regulated and temporal control of catalysis achieved. The system can be pulsed with chemical fuel several times in succession, with each pulse activating catalysis for a time period determined by the amount of fuel added. Dissipative catalysis by synthetic molecular machines has implications for the future design of networks that feature communication and signaling between the components.

The isomerization of epoxides to aldehydes using the readily available Crabtree’s reagent is described. The aldehydes were transformed into synthetically useful amines by a one-pot reductive amination using pyrrolidine as imine-formation catalyst. The reactions worked with low catalyst loadings in very mild conditions. The procedure is operationally simple and tolerates a wide range of functional groups. A DFT study of its mechanism is presented showing that the isomerization takes place via an iridium hydride mechanism with a low energy barrier, in agreement with the mild reaction conditions.

We report on a switchable rotaxane molecular shuttle that features a pseudo-meso 2,5-disubstituted pyrrolidine catalytic unit on the axle whose local symmetry is broken according to the position of a threaded benzylic amide macrocycle. The macrocycle can be selectively switched (with light in one direction; with catalytic acid in the other) with high fidelity between binding sites located to either side of the pyrrolidine unit. The position of the macrocycle dictates the facial bias of the rotaxane-catalyzed conjugate addition of aldehydes to vinyl sulfones. The pseudo-meso non-interlocked thread does not afford significant selectivity as a catalyst (2-14 % ee), whereas the rotaxane affords selectivities of up to 40 % ee with switching of the position of the macrocycle changing the handedness of the product formed (up to 60 % Delta ee).
