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.

alpha-Alkylation of arylacetonitriles with primary alcohols catalyzed by backbone modified N-heterocyclic carbene iridium(I) complexes

A series of backbone-modified N-heterocyclic carbene (NHC) complexes of iridium(I) (1d-f) have been synthesized and characterized. The electronic properties of the NHC ligands have been assessed by comparison of the IR carbonyl stretching frequencies of the in situ prepared [IrCl(CO)(2)(NHC)] complexes in CH2Cl2. These new complexes (1d-f), together with previously prepared 1a-c, were applied as catalysts for the alpha-alkylation of arylacetonitriles with an equimolar amount of primary alcohols or 2-aminobenzyl alcohol. The catalytic activities of these complexes could be controlled by modifying the N-substituents and backbone of the NHC ligands. The NHC-Ir-I complex 1f bearing 4-methoxybenzyl substituents on the N-atoms and 4-methoxyphenyl groups at the 4,5-positions of imidazole exhibited the highest catalytic activity in the alpha-alkylation of arylacetonitriles with primary alcohols. Various alpha-alkylated nitriles and aminoquinolines were obtained in high yields through a borrowing hydrogen pathway by using 0.1 mol% 1f and a catalytic amount of KOH (5 mol%) under an air atmosphere within significantly short reaction times.

Oxidize Amines to Nitrile Oxides: One Type of Amine Oxidation and Its Application to Directly Construct Isoxazoles and Isoxazolines

A facile oxidative heterocyclization of commercially available amines and tert-butyl nitrite with alkynes or alkenes leading to isoxazoles or isoxazolines is described. The unprecedented strategy of the oxidation of an amine directly to a nitrile oxide was used in this cyclization process. This reaction is highly efficient, regiospecific, operationally simple, mild, and tolerant of a variety of functional groups. Control experiments support a nitrile oxide intermediate mechanism for this novel class of oxidative cyclization reactions. Moreover, synthetic applications toward bioactive molecular skeletons and the late-stage modification of drugs were realized.

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. you can also check out more blogs about 590-17-0. Quality Control of 2-Bromoacetonitrile.

Cu(OTf)(2)-Mediated Cross-Coupling of Nitriles and N-Heterocycles with Arylboronic Acids to Generate Nitrilium and Pyridinium Products**

Metal-catalyzed C-N cross-coupling generally forms C-N bonds by reductive elimination from metal complexes bearing covalent C- and N-ligands. We have identified a Cu-mediated C-N cross-coupling that uses a dative N-ligand in the bond-forming event, which, in contrast to conventional methods, generates reactive cationic products. Mechanistic studies suggest the process operates via transmetalation of an aryl organoboron to a Cu-II complex bearing neutral N-ligands, such as nitriles or N-heterocycles. Subsequent generation of a putative Cu-III complex enables the oxidative C-N coupling to take place, delivering nitrilium intermediates and pyridinium products. The reaction is general for a range of N(sp) and N(sp(2)) precursors and can be applied to drug synthesis and late-stage N-arylation, and the limitations in the methodology are mechanistically evidenced.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 590-17-0. Application In Synthesis of 2-Bromoacetonitrile.

Novel one-pot approach to 2-aminofuran derivatives via multicomponent reaction of 3-hydroxy-4H-pyran-4-ones, alpha-ketoaldehydes and methylene active nitriles

A novel efficient one-pot method for the preparation of 2-aminofurans was developed based on multi-component reaction of 3-hydroxy-4H-pyran-4-ones, alpha-ketoaldehydes and methylene active nitriles. A distinctive feature of the proposed approach is the formation of 2-aminofurans in contrast to related literature methods leading to 2-aminopyrans. The advantages of this synthesis include high yields, mild reaction conditions, atom economy and easy workup procedure, which can avoid chromatographic purifications. The structure of one of the 2-aminofuran derivatives was determined by X-ray diffraction. (C) 2020 Elsevier Ltd. All rights reserved.

Enhanced toughness and thermal properties of bismaleimide resin based on the synergistic effect of reactive amino-terminal poly(phthalazinone ether nitrile sulfone) and bisallyl bearing diphenol group

Bismaleimide (BMI) resins have poor toughness due to their high crosslink density, which limits their wide development and application. In this study, the amino-terminated poly(phthalazinone ether nitrile sulfone) (PPENS-DA) resin was designed and the curing agent of 3,3 ‘-diallyl-4,4 ‘-biphenol (DABP) was synthesized to toughen N,N ‘-(4,4 ‘-diphenylmethane) bismaleimide (BDM) resin. The impact strength, flexural strength and fracture surface structures of the DABP/BDM and PPENS-DA/DABP/BDM blends were studied. The results showed that the notched impact strength of the blends with 10-phr PPENS-DA is 4.98 kJ/m(2), which was 36% higher than that of pristine BDM/DABP blend and 200% higher than that of the 2,2 ‘-diallyl bisphenol A (DABPA) modified BMI resin system. The glass transition temperature (T-g) has been improved from 247 to 269 degrees C for the blend system as evidenced by DMA. Rheological behavior analysis indicated that the blend system has a broad processing window (90-175 degrees C) with low viscosity of less than 1 Pa center dot s and low curing activation energy of 67.2 kJ/mol.

Streamlined Catalytic Enantioselective Synthesis of alpha-Substituted beta,gamma-Unsaturated Ketones and Either of the Corresponding Tertiary Homoallylic Alcohol Diastereomers

A widely applicable, practical, and scalable strategy for efficient and enantioselective synthesis of beta,alpha-unsaturated ketones that contain an alpha-stereogenic center is disclosed. Accordingly, aryl, heteroaryl, alkynyl, alkenyl, allyl, or alkyl ketones that contain an alpha-stereogenic carbon with an alkyl, an aryl, a benzyloxy, or a siloxy moiety can be generated from readily available starting materials and by the use of commercially available chiral ligands in 52-96% yield and 93:7 to >99:1 enantiomeric ratio. To develop the new method, conditions were identified so that high enantioselectivity would be attained and the resulting alpha-substituted NH-ketimines, wherein there is strong C=N -> B(pin) coordination, would not epimerize before conversion to the derived ketone by hydrolysis. It is demonstrated that the ketone products can be converted to an assortment of homoallylic tertiary alcohols in 70-96% yield and 92:8 to >98:2 dr-in either diastereomeric form-by reactions with alkyl-, aryl-, heteroaryl-, allyl-, vinyl-, alkynyl-, or propargyl-metal reagents. The utility of the approach is highlighted through transformations that furnish other desirable derivatives and a concise synthesis route affording more than a gram of a major fragment of anti-HIV agents rubriflordilactones A and B and a specific stereoisomeric analogue.

Monoanion-regulated high-voltage nitrile-based solid electrolyte with compatible lithium inertness

High-voltage plastic solid electrolytes (PSEs) have emerged as appealing candidates for energy-dense Li-metal batteries, but their inherent instabilities toward reductive Li anodes pose a hurdle to practical application. Herein, we report the monoanion-regulated design of a lithium-inert, high-voltage PSEs, demonstrated with a nitriledecorative PSEs (CN-PSEs) driven by BF2C2O4- monoanion. The monoanion-induced shielding layer helps to smooth lithium deposition, suppress the plastic matrix depletion, and thus retain robust Li/CN-PSEs interface even after cycling up to 1600 h in Li/Li cell, while the high-polarity nitrile group can support ion conduction and high-voltage tolerance up to 5.25 V. Benefit from the synergy, all-solid-state batteries with CN-PSEs show the superior cycling (300 cycles at 25 degrees C). This effective strategy provides a novel design principle for high-voltage PSEs to address the poor reductive stability.

Synthesis of Nitrile Bearing Acyclic Quaternary Centers through Co(III)-Catalyzed Sequential C-H Bond Addition to Dienes and N-Cyanosuccinimide

Herein we disclose a three-component strategy to access quaternary centers bearing nitriles by cobalt-catalyzed C-H bond activation and sequential addition to internally substituted 1,3-dienes and an electrophilic cyanating reagent with high regio and stereocontrol. 2-Aryl and alkyl monosubstituted dienes provide alpha-aryl and alpha-alkyl alpha-methyl-substituted nitriles, respectively. An even wider variety of functionality can be installed at the quaternary carbon by using 1,2-disubstituted dienes. The synthetic utility of the nitrile products was successfully demonstrated by various transformations, including conversions to gamma-lactones and tetrazoles. The observed connectivity in the products along with studies with deuterium labeled reactants provide insight into the mechanism. Formation of a 7-membered cobaltacycle by C-H activation and migratory insertion of the diene is followed by beta-hydride elimination and hydride reinsertion to give a 6-membered cobaltacycle that then reacts with the cyanating agent.

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. you can also check out more blogs about 590-17-0. Safety of 2-Bromoacetonitrile.
