Transition-metal-free synthesis of primary to tertiary carboxamides: A quick access to prodrug-pyrazinecarboxamide

One-pot expedient and direct carbamoylation of heterocyclics is described. The transformation is realized via direct dehydrogenative aminocarbonylation of heterocyclic compounds under transition-metal-free conditions. This method is regioselective and the protocol is proved to be scalable on a gram scale. Further, the therapeutically useful antitubercular agent pyrazinecarboxamide is successfully synthesized by employing this protocol. (C) 2017 Elsevier Ltd. All rights reserved.

A concise synthesis of peramine, a metabolite of endophytic fungi

The total synthesis of peramine, a natural product isolated from an endophytic fungi, has been achieved in four steps and 34% overall yield from known compounds. The key step was the one-pot construction of the pyrrolopyrazinone ring from pyrrole amide and propargyl bromide. The preparation of peramine-d(4) as an internal standard for quantitative analysis by MS is also described.

Burn-related Collagen Conformational Changes in ex vivo Porcine Skin using Raman Spectroscopy

This study utilizes Raman spectroscopy to analyze the burn-induced collagen conformational changes in ex vivo porcine skin tissue. Raman spectra of wavenumbers 500-2000 cm(-1) were measured for unburnt skin as well as four different burn conditions: (i) 200 degrees F for 10 s, (ii) 200 degrees F for the 30 s, (iii) 450 degrees F for 10 s and (iv) 450 degrees F for 30 s. The overall spectra reveal that protein and amino acids-related bands have manifested structural changes including the destruction of protein-related functional groups, and transformation from et-helical to disordered structures which are correlated with increasing burn severity. The deconvolution of the amide I region (1580-1720 cm(-1)) and the analysis of the sub-bands reveal a change of the secondary structure of the collagen from the alpha like helix dominated to the beta-aggregate dominated one. Such conformational changes may explain the softening of mechanical response in burnt tissues reported in the literature.

Protein crosslinking improves the thermal resistance of plastocyanin immobilized on a modified gold electrode

Increasing the thermal stability of immobilized proteins is a motivating goal for improving the performance of electrochemical biodevices. In this work, we propose the immobilization of crosslinked plastocyanin from the thermophilic cyanobacterium Phormidium laminosum by simultaneous incubation of a mixture of plastocyanin and the coupling reagents. The thermal stability of the so built covalently immobilized protein films has been assessed by cyclic voltammetry in the 0-90 degrees C temperature range and has been compared to that of physisorbed films. It is shown that the protein loss along a thermal cycle is significantly reduced in the case of the crosslinked films, whose redox properties remain unaltered along a cyclic heating-cooling thermal scan, and can withstand the contact with 70 degrees C solutions for four hours. Comparison of thermal unfolding curves obtained by circular dichroism spectroscopy of both free and crosslinked protein confirms the improved thermic resistance of the crosslinked plastocyanin. Notably, the electron transfer thermodynamics of physisorbed and crosslinked plastocyanin films are quite similar, suggesting that the formation of intra- and inter-protein amide bonds do not affect the integrity and functionality of the copper redox centers. UV-Vis absorption and circular dichroism measurements corroborate that protein crosslinking does not alter the coordination geometry of the metal center. (C) 2018 Elsevier B.V. All rights reserved.

Dry-Gel Conversion Synthesis of Zr-Based Metal-Organic Frameworks

UiO-66 was successfully synthesized in the absence of any amide solvents and hydrochloric acid by using the dry-gel conversion (DGC) method for the first time. The prepared UiO-66 samples (denoted as UiO-66-DGC) were characterized by XRD, SEM, TGA, CO2 adsorption, NH3-TPD, and N-2 adsorption. The results showed that the UiO-66-DGC-E sample synthesized by using ethanol as solvent has similar crystallinity and morphology to the UiO-66 sample prepared by the conventional solvothermal method (denoted as UiO-66-S). However, it has more linker deficiencies, indicating the presence of more defects exposed in Zr clusters. As a resut, the prepared UiO-66-DGC-E sample exhibited high catalytic activity and reusability in esterification. This preparation method provides a new alternative method for the efficient and eco-friendly synthesis of metal organic frameworks (MOFs) and modification of their properties.

Photoredox-Mediated Remote C(sp(3))-H Heteroarylation of N-Alkyl Sulfonamides

A Minisci-type delta-selective C(sp(3))-H heteroarylation of sulfonyl-protected primary aliphatic amines with N-heteroarenes under photoredox-catalyzed conditions was developed. The reaction typically uses a slight excess of amine reactant. The use of benziodoxole acetate (BI-OAc) oxidant and hexafluoroisopropanol solvent is critical to achieve high yield. Besides methylene C-H bonds, heteroarylation reactions of delta methyl C-H bonds also worked under more forced conditions. The reactions show a broad scope for both amine and N-heteroarene substrates, offering a straightforward method for synthesis of complex delta-heteroarylalkylmines from simple precursors.

Half-sandwich ruthenium complexes with oxygen-nitrogen mixed ligands as efficient catalysts for nitrile hydration reaction

Three ruthenium(II) p-cymene complexes containing oxygen-nitrogen mixed ligands [Ru(p-cymene)LCI] [HL = 2-(4,5-dihydrooxazol-2-yl)phenol (2a); HL = 2-(4,5-dihydrothiazol-2-yl)phenol (2b); HL = 2-(5,6-dihydro-4H-1,3-oxazin-2-yl)phenol (2c)] have been synthesized and characterized. All half-sandwich ruthenium complexes were fully characterized by H-1 and C-13 NMR spectra, elemental analyses and infrared spectrometry. The molecular structure of ruthenium complex 2c was further confirmed by single crystal X-ray diffraction methods. Furthermore, these half-sandwich ruthenium complexes are active catalysts for the hydration of nitriles to amides in the presence of sodium hydroxide in isopropanol. (C) 2017 Elsevier Ltd.

Catalytic intermolecular aldol reactions of transient amide enolates in domino Michael/aldol reactions of nitroalkanes, acrylamides, and aldehydes

Three-component reactions of nitroalkanes, acrylamides, and aldehydes by using a catalytic amount of KOH in DMSO gave beta ‘-hydroxy-gamma-nitro amides. Mechanistic studies suggested that the reactions proceeded by domino Michael/aldol reactions. The highly nucleophilic nature of transient amide enolates that were formed by Michael addition of nitronate anions to acrylamides in DMSO enabled the realization of catalytic intermolecular aldol reactions of amide enolates in the presence of acidic nitroalkanes.

The enthalpies of dilution of some dipeptides in water at 298.15 K

The enthalpies of dilution of glycyl L-alpha-alanine, glycyl-L-alpha-leucine and glycyl-L-glutamine have been measured in water at T = 298.15 K. The experimental results were used to calculate the enthalpic coefficients of the interactions between dipeptides molecules in water based on McMillan-Mayer’s model. The values of the interaction parameters were interpreted in terms of the hydrophobic or hydrophilic properties of the amino acid side chins in the examined dipeptide molecules and the influence on their interactions with each other in water.

An efficient and simple synthetic protocol for the synthesis of a number methyl esters of 2-(N-hydroxycarbamimidoyl)benzoyl-substituted (S)–amino acids via subsequent coupling and hydroxyamination of 2-cyanobenzamide derivatives has been developed. Comparative analysis of three pseudopeptide series based on 2-cyano- and 2-amidoxime-substituted benzoic acid and its pyridine and pyrazine counterparts has been provided and it has revealed a practical advantage of the benzoic acid derivatives due to their greater availability. The impact of the nitrogen atom in the aromatic ring on the trans/cis-amide equilibrium in the proline derivatives is discussed. [GRAPHICS]
