Nitriles as radical acceptors in radical cascade reactions

The cyano group is a valuable and readily available functional group for the preparation of various functional groups, such as amines, carboxylic acids, and ketones. In recent decades, the radical cascade reaction has emerged as a versatile tool to prepare a large variety of functional molecules. The application of the cyano group as a radical acceptor in cascade reactions provides diverse opportunities for the convenient construction of various important heterocycles and carbocycles. Such synthetic strategies will open new ways for the rapid buildup of molecular complexity. The focus of this review is the summary of the dynamic field of radical cascade processes using the cyano group as a radical acceptor, which has not been well documented so far.

Blooming-forming cyanobacteria pyrolysis over Ni-Al layered double oxides/MCM-41 for nitriles under nitrogen and methanol atmosphere

Blooming-forming cyanobacteria were catalytically pyrolyzed over Ni-Al layered double oxides/MCM-41 (NiAl-LDO/MCM-41) composites with nitrogen or methanol as sweep gas for the production of nitrogenous compounds. The effect of catalysts and gas atmosphere on the product distribution and the formation of nitrogenous compounds was investigated. The results showed that the amount of nitrogenous compounds increased with the increase of catalyst/cyanobacteria ratio; liquid yields of about 50% were obtained over NiAl-LDO/MCM-41 under both nitrogen and methanol atmosphere. However, composites of the hydrocarbons and aromatic compounds in bio-oil under methanol atmosphere were lower than those under nitrogen atmosphere. Nitrogenous compound content of 78.6%, especially a 68.5% content of nitriles with low oxygen content and acidity, demonstrated that the bio-oil obtained was promising in producing value-added platform chemicals.

Hydrothermal alkaline conversion of actual acrylonitrile wastewater to organic acids

Acrylonitrile wastewater is a kind of highly toxic industrial wastewater, but it contains a lot of valuable chemical materials. In this study, by using the most promising hydrothermal technology, we investigated the best reaction conditions and possible reaction pathways for the conversion of the three nitrites (acrylonitrile, acetonitrile, and succinonitrile) to organic acids under alkaline hydrothermal conditions. Then, the reaction conditions for the conversion of actual acrylonitrile wastewater to organic acids were further optimized. The actual wastewater of acrylonitrile was converted into 1.33 x 10(4) mg/L acrylic acid, 1.98 x 10(4) mg/L formic acid and 9.40 x 10(3) mg/L acetic acid at optimal reaction conditions (reaction temperature 300 degrees C, reaction time 90 s, and initial NaOH concentration 1.0 mol/L). It is the theoretical basis of the application of the hydrothermal alkali-catalyzed method in the acrylonitrile wastewater resource engineering.

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.

Cycloadditions of Alkenylboronic Derivatives

The literature on cycloaddition reactions of boron-containing alkenes is surveyed with 132 references. The data are categorized according to the reaction type ([2+1], [2+2], [3+2], [4+2], and [4+3] cycloadditions). The cyclopropanation and the Diels-Alder reactions of alkenylboronic derivatives have been studied more or less comprehensively, and for some substrates, they can be considered as convenient methods for the rapid regio- and stereoselective construction of even complex cyclic systems. Other types of the cycloadditions, as well as mechanistic aspects of the processes, have been addressed less thoroughly in the previous works.

Spectroscopic calculations, Hirshfeld surface analysis, and molecular docking studies of anticancer 6-(4-Aminophenyl)-4-(4-methoxyphenyl)-2-methoxynicotinonitrile

The title compound 6-(4-Aminophenyl)-4-(4-methoxyphenyl)-2-methoxynicotinonitrile was deliberated by proton nuclear magnetic resonance, ultraviolet-visible, and Fourier transform infrared spectroscopy techniques. The theoretical optimized geometrical parameters (bond lengths, bond angles and dihedral angles), vibrational wavenumbers, and the non-linear optical properties were calculated using the density functional theory with the Becke, 3-parameter, Lee-Yang-Parr functional method. Hirshfeld surface and two-dimensional fingerprint plot analyses have been performed to study the nature of intermolecular interactions within the crystal structure. The ultraviolet-visible spectrum, global chemical reactivity descriptors, the highest occupied molecular orbital and the lowest unoccupied molecular orbital energies in acetonitrile solvent have performed by Time-Dependent Density Functional Theory approach. The molecular electrostatic potential used to predict the reactive sites indicates that the nitrogen atom of the nitrile group is prone to electrophilic attack, and the hydrogen atoms belonging to the amino group to nucleophilic attack. The first-order hyperpolarizability value indicates that the title compound is a useful claimant as non-linear optical material studies. The reduced density gradient function based on electron density provides a simple, clear, and practical method to research non-covalent interactions was investigated. Molecular docking studies of the title compound have been performed, which suggests that the title molecule may act as a potential anticancer agent.

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.

Synthetic Studies on Cyclocitrinol: Construction of the ABC Ring System Based on Epoxy-Nitrile Cyclization

The stereoselective synthesis of a model compound containing the ABC ring system of cyclocitrinol was accomplished. After connecting a C ring allyltitanium segment with an A ring bi-cyclo[4.1.0]heptanone segment, the seven-membered B ring moiety was constructed by an intramolecular cyclization reaction of an epoxy nitrile. The enone moiety was introduced through an oxidative decyanation reaction, and the bicyclo[4.4.1]undecane skeleton with the highly strained olefin moiety was formed through a ring-opening reaction of the bicyclo[4.1.0]heptane substructure.
