A theoretical investigation of iron-catalyzed selective hydrogenation of nitriles to secondary imines

The mechanism of the transition metal iron complex [(iPr-PNP)Fe(H)Br(CO)] catalyzed reaction of selective hydrogenation of nitriles to secondary imines has been investigated with the M06-2X function. The results indicate that the reaction involves two basic processes: (i) A catalyzed p-bromobenzonitrile to benzaldimine and primary amine transformation; (ii) condensation of benzaldimine with a primary amine to afford secondary imine. The calculated barrier of transition metal-catalyzed condensation reaction of benzaldimine with a primary amine, 30.6 kcal/mol, indicates that the condensation reaction is feasible under experiment conditions. The theoretical results provide a deeper understanding of the mechanism and fully explain the experimental facts.

Highly Selective Sub-Nanomolar Cathepsin S Inhibitors by Merging Fragment Binders with Nitrile Inhibitors

Pharmacological inhibition of cathepsin S (CatS) allows for a specific modulation of the adaptive immune system and many major diseases. Here, we used NMR fragment screening and crystal structure-aided merging to synthesize novel, highly selective CatS inhibitors with picomolar enzymatic Ki values and nanomolar functional activity in human Raji cells. Noncovalent fragment hits revealed binding hotspots, while the covalent inhibitor structure-activity relationship enabled efficient potency optimization.

Scalable synthesis of a tetrasubstituted 7-azabenzofuran as a key intermediate for a class of potent HCV NS5B inhibitors

A series of tetrasubstituted 7-azabenzofurans displays remarkable pan-genotype inhibition of HCV NS5B polymerase. One of them has been identified as a potential clinical candidate. Completely different from the original synthesis of a common and key intermediate for this class of compounds, two novel and improved synthetic approaches are developed. Almost every step of the synthesis has been optimized, including several important but not fully explored transformations, such as radical bromination with methyl pyridine and cyanide substitution with TMSCN. The 7-azabenzofuran core is prepared by an acylation-heterocyclization reaction, using acyl chloride as both the reactant and the activation reagent for the N-oxide substrate. Compared with the BMS synthesis, the overall yield has been tripled, and those harmful or cost-effective synthetic steps have been reduced. Furthermore, a transition-metal-free synthetic method for the construction of 3-cyano substituted 7-azabenzofurans is presented. (C) 2020 Elsevier Ltd. All rights reserved.

Aramid nanofiber reinforced nitrile rubber assisted by cellulose nanocrystals

A fiber-reinforced rubber composite was prepared by mixing aramid nanofibers (ANF) suspension and nitrile rubber (NBR) latex. The effects of ANF content and corresponding surface modification on the microstructure, vulcanization performance, processing and mechanical properties of composite materials, were systematically investigated. We found that, compared with commonly used short-cut aramid fibers, ANF fillers tend to form a stronger filling network within NBR matrix, resulting in a pronounced Payne effect. By improving the interfacial adhesion via dopamine (DA) coating onto ANF surface, the tensile strength can be further enhanced as expected. Besides, to eliminate the detriment of mechanical performance due to residual sodium polyacrylate in the course of flocculation, cellulose nanocrystal (CNC) was adopted to serve as a thickener during solution mixing. The incorporation of CNC can significantly improve the mechanical properties, which identifies a synergistic reinforcement effect arising from the cooperation of two types of fillers.

Highly functionalized N-1-(2-pyridinylmethyl)-3,5-bis[(E)- arylmethylidene]tetrahydro-4(1H)-pyridinones: Synthesis, characterization, crystal structure and DFT studies

Highly functionalized N-1-( 2-pyridinylmethyl)-3,5-bis [(E)-methoxy/fluorophenylmethylidene]-tetrahydro-4(1H)-pyridinones (5a and 5b) have been synthesized in good yields. The molecular structure of the synthesized compounds was elucidated by NMR spectroscopy and further confirmed by single crystal Xray crystallographic studies. The Hirshfeld analysis reveals that the molecular packing of 5a is mainly controlled by N center dot center dot center dot H (4.9%), C center dot center dot center dot H (30.6%) and H center dot center dot center dot H (52.4%) contacts whereas the molecules are packed by strong F center dot center dot center dot H (16.8-16.9 %), N center dot center dot center dot H (5.4%) and O center dot center dot center dot H (5.2-5.4%) as well as weak C center dot center dot center dot O (3.9-4.5%), H center dot center dot center dot H (39.7-39.9%) and C center dot center dot center dot H (24.8-25.8%) contacts in 5b. DFT calculations are used in order to predict the electronic properties of studied compounds. The NMR data obtained experimentally correlated well with the calculated findings. (C) 2020 Elsevier B.V.

Radical Rearrangement of Aryl/Alkylidene Malononitriles via Aza Michael Addition/Decynoformylation/Addition Sequence: An Access to alpha-Aminonitriles and alpha-Aminoamides

An efficient, safe, and environmentally friendly tertiary butyl hydrogen peroxide (TBHP)-mediated rearrangement of aryl/alkylidene malononitrile with anilines has been developed with in situ generation of HCN as the cyanide source for the synthesis of substituted alpha-aminonitriles and alpha-aminoamide. A diverse set of alpha-aminonitriles and alpha-aminoamides was efficiently synthesized in good to excellent yields. This method features a broad substrate scope and good functional group tolerance, and the in situ-generated HCN bypasses the use of an external cyanide source.

On water palladium catalyzed diastereoselective boronic acid addition to structurally diverse cyclopropane nitriles

An efficient palladium catalyzed diastereoselective addition of arylboronic acids to complex spirocyclopropyl dinitriles is developed in the presence of a catalytic amount of 4-dodecylbenzenesulphonic acid (DBSA) as a Bronsted acid surfactant in aqueous media. The protocol is also found to be highly effective when different types of nitrile compounds and organo-boron compounds are used. The overall reaction has been found to be very cost efficient since it requires low catalyst loading, mild thermal energy and short reaction time. Wide substrate scope, operational simplicity, good to excellent product yield, and use of green solvents make the reaction a practical route to transform nitrile into a keto functionality in biorelevant heterocyclic scaffolds. The scale-up synthesis of the target scaffolds can also be achieved with ease which also signifies the practicability of this protocol.
